Abstract:- Smartphone-based indoor navigation services are desperately needed in indoor environments. However, the adoption of them has been relatively slow, due to the lack of fine-grained and up-to-date indoor maps, or the potentially high deployment and maintenance cost of infrastructure-based indoor localization solutions. This work proposes ViNav, a scalable and cost-efficient system that implements indoor mapping, localization and navigation based on visual and inertial sensor data collected from smartphones. ViNav applies structure-from-motion (SfM) techniques to reconstruct 3D models of indoor environments from crowdsourced images, locates points of interest (POI) in 3D models, and compiles navigation meshes for path finding. ViNav implements image-based localization that identifies users’ positions and facing directions, and leverages this feature to calibrate dead-reckoning-based user trajectories and sensor fingerprints collected along the trajectories. The calibrated information is utilized for building more informative and accurate indoor maps, and lowering the response delay of localization requests. According to our experimental results in a university building and a supermarket, the system works properly and our indoor localization achieves competitive performance compared with traditional approaches: in a supermarket, ViNav locates users within 2 seconds, with a distance error less than 1 meter and a facing direction error less than 6 degrees.

Abstract:- Paying for parking is a waste of time and an inconvenient procedure. To solve this problem we introduce our system “An android application for smart parking with efficient space management” which offers full automation of paying for parking. Our solution will change the life of every driver. This will not waste their time anymore searching for a parking meter because the parking meter will find them. They will not have to pay a parking ticket again since they get the nearest place for parking using our system and pay parking fees for the place. There is also a module, the user can give their place for parking and they get rent for the parking slot, if the place is in congested areas then the amount of rent will also increase. Security is another one, we provide security for each vehicle that registered for parking. Efficient space management in the parking area is also important. That will help the application's proper working and customer satisfaction. The user first needs to register or create an account using his android phone and application. This registration will save on our server. When the time for parking the vehicle number scanned with a camera and compare with the registered number in sever, if they match then the gate automatically opens, else don't. Only after the timeout and or timeout call the vehicle can safely get out of the parking area. The cameras installed in the parking area to capture photos of the vehicle at every entering an exciting time and send them to the server. The time will also be recorded.

Abstract:- Today, most instructors in universities are found up 'til now using the normal procedures for taking understudies' interest either by getting out the understudy names or by circumventing a cooperation sheet for understudies to sign asserting their substance. Despite the monotonous issue, such technique is also at higher peril of having understudies misleading about their support, especially in a broad classroom. Consequently, a strategy for taking investment by using an application running on the Android arrange is proposed in this paper. This application, once acquainted can be used with download the understudies list from a doled out web server. In light of the downloaded once-over of understudies, the device will then act like an IMEI number for understudy compact one by one to avow and check the understudy's quintessence. The revived interest sends SMS to gatekeepers either understudy is accessible or truant. This system will shed the present issues, while also propelling a paperless area meanwhile. Since this application can be sent on educators have existing Android devices, no additional hardware cost is required.

Abstract:- Advances in Embedded systems, low-cost gas sensor, and wireless communication technologies are enabling new possibilities to develop systems that can be used to continuously monitor the health and stability of the environment we live in. Traditionally, environmental monitoring systems are expensive and are installed at fixed locations. This is a distributed approach where the measuring units are sparse and placed remotely from each other. In this paper, we present a transportable environmental monitoring system which will detect the presence of vehicular emissions which is mainly contributed by Carbon Dioxide (CO2) and Carbon Monoxide (CO) gases together with weather conditions such as temperature and relative humidity of the surrounding atmosphere. The acquired data can be transferred through a Bluetooth module to an Andriod application for continuous visualization. In addition to that, the Andriod application is also designed such that it acquires the geographical coordinates of the cell phone form the inbuilt Global Positioning System (GPS) module and can record the pollution concentration of that specific location and store the records in a designated Web server. We present a preliminary prototype of the system and discuss the implementation challenges and initial experiments.

Abstract:- In most existing remote-control services for smart home appliances, a controller outside the home network can be used to control these appliances in the home network using a remote-control support server installed on the Internet. However, if the service provider ends the service, a user cannot control these appliances from outside the home. In this paper, we propose a secure end-to-end remote-control system based on NTMobile which is a technology to achieve NAT traversal and end-to-end encrypted communication. With the proposed system, the operating android device can remotely control the smart appliances existing in the house from outside the house safely and securely without requiring a manufacturer’s remote-control server in the existing service. As a result of the operation verification and performance evaluation of the proposed system inthemobileInternetenvironment,weconfirmedthatthedevices compatible with ECHONET Lite, which is a communication standard for controlling smart home appliances and residential equipmentsfrominsidethehouse,installedundertheNATrouter can be directly controlled from outside the house within the timeout time specified by the ECHONET Lite specification.

Abstract:- The hospital emergency service remains the first choice for the vast majority of patients. The large influx of hospital emergency services, combined with the lack of health professionals, often makes the patients susceptible to excessive waiting times. As a result, their health condition may worse after triage, until they are observed by a doctor. In the developed prototype, a bracelet is placed on the patient’s wrist, which reads their vital signs, accompanied by a mobile phone with an Android application, designed to send the collected vital signs data, as well as patient's location, periodically, to a server. There is a database, with the information of all patients under care and, through a dashboard, the interface is made with the health professionals. Such interface alerts the professional whenever a situation is considered critical. The prototype was positively evaluated by the usability tests carried out and could be considered a Minimum Viable Product in the business perspective.

Abstract:- Tropical hydroponic cultivation needs to control humidity, temperature, water level, pH, and EC factors suitable for tropical climate. In order to grow qualified hydroponic plants, nutrient solution has to run through bottom channels constantly, and pH and EC factors in the solution have to control as the plant ages, the varieties of hydroponic plants and also the food safety qualification. In addition, tropical counties have hot climate almost the whole year; therefore, the greenhouse humidity and temperature have to be controlled. The power outage should be detected to avoid shutting off the nutrient solution pump. This paper proposes automatic control and management system for tropical hydroponic cultivation. The system aims to reduce information exchange of multisensor data fusion within the wireless sensor network by grouping the sensors to decide the data fusion results. It can control water level, humidity, and temperature as grower setting automatically. It also sends sensor data and status, collects pH and EC values of individual nutrient solution tank, and sends notification via Android mobile application. The data history is available on web application. This therefore is easily to monitor, manage data, and setting online. The system is tested in northern Thailand hydroponic farm. The evaluated results show that the system can decide the results from multisensor grouping as the setting correctly.

Abstract:- Various distributed sensing applications are being deployed in the context of crowd-sensing. These applications often require that sensors are mutually synchronized. However, when synchronization is required in a setting where volunteers bring their own mobile device, to contribute to a measurement campaign, several issues arise. This paper analyses and evaluates the Android mobile platform for applications which require collaborative continuous sensing. These applications rely on time synchronized devices to sample sensors at a high data rate and without discontinuities. We show that it is feasible to synchronize smartphones without limiting the system’s scalability, or introducing additional power consumption. Furthermore, the challenges related to continuous sensing in Android for crowdsensing applications are identified.

Abstract:- This project presents microcontroller based digital alternating current (AC) dimming techniques for controlling the ambient light intensity. In this work, the light intensity control is intelligently implemented by varying the AC voltage using the digitally isolated forward phase controlled gate pulses of bidirectional triode thyristor (TRIAC). The main objective of this work is to digitally control the firing angle delay of gate of TRIAC from both onsite and remote location using different methods that replaces the conventional AC dimmer. The dimming level signal is transmitted to the low cost microcontroller board from the capacitive touch sensor at the onsite location. At the remote location, dimming is performed using either the Bluetooth communication interface or web based dimming from the client computer to microcontroller board using NI (National Instruments) LabVIEW software. In order to perform onsite dimming, AC input voltage supplied to light source is varied in proportional to the time period elapsed during which the finger is placed over the capacitive touch sensor. To facilitate remote dimming, the dimming level signal is supplied from Android based smart phone having the application software for paring connection and data communication with Bluetooth transceiver interfaced with microcontroller and also the dimming signals are supplied from the client computer to microcontroller board using web publishing tool of LabVIEW.

Abstract:- In this era of rapid growth of vehicles, the ratio of road accident increases day by day. Nowadays, Traffic incidents are persistent problems in both developed and developing countries which result in huge loss of life and property. No one in this world is ready to gaze what’s happening around them. Nobody cares even when an accident occurs. This paper provides an innovative solution by developing an Accident Alert Message System using an Android Smartphone Application that can be used from the accident zone. The application uses GPS technology for location mapping and sends an alert and notification of an accident. The generated accident alert message is endorsed by the nearby registered users who also witness the accident to ensure the increased reputation of the message. Based on the endorsement of the message, the system will instantly transmit the location of the accident to the nearby emergency services. In this case, users usually lack the enthusiasm to generate or endorse alert messages because they might fear that their privacy will be breached. At the same time, users do not benefit from generating or endorsing alert messages which also makes them lack the enthusiasm or motivation to respond to messages. In order to provide a solution to resolve these issues, this paper presents a novel privacy-preserving Blockchain – Based Incentive Mechanism for Accident Alert Message System. The main objective of the paper is to encourage the users to generate and endorse accident alert messages from the accident zone without revealing the user’s identity. Also, some incentives to the users are paid to the message generators and endorsers and the transactions get stored based on the Blockchain technology; hence the privacy of the user is preserved. Our proposed system ensures the reliability of alert messages without revealing the privacy of the user and is reliable and efficient in the non-fully-trusted environment.

This system transmits the vital signs of the neonate such as body temperature and pulse rate to the Internet of Things (IoT) called ThingSpeak. The body temperature and the pulse rate will be detected by LM35 temperature sensor and pulse sensor respectively. These information will be sent to the IoT via ESP8266 Wi-Fi Shield. IoT helps the doctors and nurses to be connected with the neonate’s vital signs and it is helpful in monitoring the neonates at anytime and anywhere through the internet. The percentage difference between LM35 temperature sensor and digital thermometer is less than 3% while the pulse rate can be varied according to the physical activity. This develops system will providing efficiency and reliability which will play a vital role for better care.

Abstract:- The idea behind the face recognition system is the fact that every individual has a unique face. Like the fingerprint, an individual's face has many unique structures and features. Facial authentication and facial recognition are challenging tasks. For facial recognition systems to be reliable, they must work with great precision and accuracy. Images captured taking into account different facial expressions or lighting conditions allow greater precision and accuracy of the system compared to a case where only one image of each individual is stored in the database. The face recognition method handles the captured image and compares it to the images stored in the database. If a matching template is found, an individual is identified. Otherwise, the person is reported as unidentified. This paper describes and explains in detail the entire process of developing Android mobile application for recognizing person’s gender, age and face. Face detection and recognition methods that have been used are described and explained as well as development tools used in the development of Android mobile application. The software solution describes the details of using the OpenCV library and shows the actual results of the mobile application through the images.

Abstract:- Disaster management is a complex and interesting domain which deals with abnormal, extremely critical and challenging situations. It has always been a worldwide concern and considered one of the leading causes of death and injuries around the world. During disasters, continuous connectivity plays a vital role in rescue operations. However, maintaining stable and continuous connectivity in disasters is unguaranteed because of the possible failure of infrastructure network caused by disasters. Hence depending on disaster management systems that are built on infrastructure networks is impractical and unfeasible. Utilizing alternative solutions like mobile Ad-hoc networks may substitute the infrastructure network. In this paper, we utilize WiFi direct technology which is known for its superiority over other similar ad-hoc network technologies to develop a disaster management system. The System is specifically developed to provide a stable communication channel between victims and rescuers. Additionally, we propose an optimization to WiFi direct network to enable the inter-group communication between different WiFi direct groups using WiFi legacy. Using this hybrid solution of the two technologies (WiFi legacy and WiFi Direct), we developed an android disaster management system that is more robust and resilient to damage. Experimental results demonstrate that the system achieves improvement in terms of energy consumption, delay and reliability comparing to existing works.
