COMMUNICATION IN A SELF-RELIANT AD HOC NETWORK

摘要

The project aims to provide communication anywhere anytime when the telecommunication network is not available for example after a disaster, or in sparsely populated areas. Mobile phones normally can't be used when cellular networks fail as in case of disaster. This means that millions of people around the world are not able to communicate, when they need it most as most of its functionality are supported either by Internet or the GSM/CDMA network. The paper proposes idea to allow the user to communicate without any infrastructure with other users using the Wi-Fi connection of smart phones to create a self-reliant ad hoc network created which will enable the user to transmit data even in absence of Internet or the GSM/CDMA network. The user can send text messages, audio, video and other files. In this network congestion can be solved with help of ATM network algorithm. This application is developed specifically for android based cellular devices as there is no direct way to create an ad hoc network in android devices. The integrated approach of a mobile app and ad hoc network can save life and reduce the time needed for critical service to be restored.
