This paper presents an obstacle detection system able to permit the visually impaired user to get information on the surrounding complex environment. The system also allows setting an active mobile connection with the distant assistant guide. A low-cost ultrasound microcontroller based system, capable of detecting grounded or raised obstacles up to a few meters in front of the subject, is proposed...
GPS positioning technology and GSM wireless communication technology have been widely used in the military field and urban transportation and other civilian areas. Aiming at the singularity of handheld positioner function on the market, this paper designs a combination device of handheld positioner and tracker. By extracting GPS navigation information frame parameters and GSM wireless data transmission...
Now a days, the number of two wheelers in India has drastically increased to a great extent. Due to which automobile users are undergoing numerous road accidents thereby causing death. The first and the foremost precaution to avoid dea this to protectour head, therefore we go for helmets. Even though helmets are available everywhere we are not using it properly. This system is a special idea which...
The custom of pilgrimage is widespread all over the world, e.g. Kumbh Mela in India, Hajj in Saudi Arabia. These are the peaceful gatherings wherein, millions of people from all corners of the world come to perform their holy rituals. However, during these events, pilgrims getting lost in the crowd, medical emergencies and stampede are likely to happen. In such incidents, authorities involved in the...
Now-a-days children and women are facing many security related problems. In such situations, they are helpless and don't have any way to protect them or inform it to their family members, neighbours or police station and they feel as handicaps. Hence there should be a system to protect them in such times. So this system helps them to seek help in any critical situation. For that, the system contains...
Many articles have been published on TDM SDH backhaul synchronization and few on GSM network (NW synchronization), but very few articles have appeared on experimental trails conducted to show the impact of clock quality and Synchronization on GSM network performance specifically with regard to network hygiene and call quality(call drops and hand overs). In this paper an experimental trail conducted...
Positioning techniques are known in a wide variety of wireless radio access technologies. Traditionally, Global Positioning System (GPS) is the most popular outdoor positioning system. Localization also exists in mobile networks such as Global System for Mobile communications (GSM). Recently, Wireless Local Area Networks (WLAN) become widely deployed, and they are also used for localizing wireless-enabled...
The development of a positioning algorithm on the board of a moving object using the information about the direction of signal reception from global system for mobile base stations. The developed system may be used as the effective and reliable method of positioning. Mobile module can help to solve all the types of positioning problems.
When disasters occurs, cellular network might be down and cannot serve subscribers anymore. On the other hand, many victims trapped in a wreckage might still have access to their mobile phone. An OpenBTS-based cellular network has been long before known as an ideal solution to rapidly deploy emergency GSM cellular network in situation after disaster. We propose to deploy a mobile OpenBTS along with...
Recently, all over the world crime against children is increasing at higher rates and it is high time to offer safety support system for the children going to schools. This paper focuses on implementing children tracking system for every child attending school. However the existing systems are not powerful enough to prevent the crime against children since these systems give information about the...
Avoiding Vehicle Theft is making buzz in present automobile industry. Design and development of a theft control system for an automobile, can be achieved by making use of GPS feature of mobile phone. The developed system makes use of an mobile phone that is embedded in the vehicle with an interfacing to Engine Control Module(ECM) through Control Area Network (CAN) Bus, which is in turn, communicated...
The “geo-encryption” or “location-based encryption” is a security algorithm that limits the access or decryption of information content to specified locations and/or times. This algorithm does not replace any of the conventional cryptographic algorithms, but instead adds an additional layer of security to exist stack. GSM is chosen as a case study to implement geo-encryption in its key generation...
A remote exploration and control system has been developed using web Application, web server, database, GSM network, and Android mobile phone. Web application is used to control remotely an Android mobile phone and electrical devices connected with the mobile phone. Firstly, command is sent from the web Application and saved in database. The Android mobile phone reads the sent command from database...
In this paper, a system is presented which supports mobile assisted living by combining the advantages of smart sensors, GPS and GSM technology. The system can detect abnormal situations with the person wearing the wearable part of the system (e.g. abnormal heart rate) and send this information to the nursing home so that appropriate action can be taken immediately. The information sent by the system...
In this paper, we consider the problem of positioning, travel direction detection and speed estimation of GSM-based mobile phones. Many techniques are proposed using several technologies like GSM, UMTS or WiFi. Once these technologies are mature enough to be deployed, they will have significant impact on automotive telematics and modern public transit systems. We produce a technique for speed estimation...
The use of mobile devices has become a part of our daily routine. Recently, mobile devices like mobile phones or portable digital displays (PDAs) are equipped with global positioning system (GPS) receptors that allow us to get the device's geographic position in real time. Location Based Services (LBS) are regarded as a key feature of many future mobile applications. GPS serves well for most outdoor...
This document provides detail on the implementation of a location awareness system which gives the user's current location, sends this location using SMS (Short Message Service) plus sharing location with friends and family and view them on Google maps. Users can also take benefit of this application in emergency situations by using emergency feature of this application. To get the location coordinates,...
“Technology does not drive change, it enables change.” The primary purpose of Technology is its implementation in day-to-day life wherein it could enhance the lifestyle as well as provide better safety and performance to its end users. The government has enforced stringent laws against usage of mobile phones while driving a vehicle. Yet, there seems to be a sense of casualness amongst our citizens...
Taking advantage of the technology of wireless sensor networks (WSNs), the radio frequency identification (RFID) and global system for mobile communication(GSM), this paper constructs a wireless communication and intelligent application system. WSNs combines with RFID system collect basic materials property data, materials environmental data perceived by all kinds of sensors and materials coordinate...
In this paper a system level analysis and implementation of two-layer mobile wireless sensor network architecture is proposed for tracking and environmental supervision applications. It uses a mobile Master Sensor Node (MSN) that collects information inside a Sensor Area Network (SAN) where many semi-passive Slave Sensor Nodes (SSN) are deployed. The collected information is sent through a Wireless...
