Efficient routing in disaster area network and human mobility using wireless adhoc networks

Abstract

quotThe recent disasters, whether natural or man-made, have shown that the existing communication infrastructure was totally destroyed or stopped functioning due to over usage. Communication services must be facilitated for rescue and relief workers to collect the information about the victims and damages of property. Victims would like to send the messages to family and friends about their well-being. The information collected from the disaster scenario must be sent to the main control station connected with the outside world, for quick actions and coordination. The network of human being acting as rescue workers, relief workers and victims, and vehicles such as ambulances and providing relief goods, can be created on a temporary basis. The unique characteristic of disaster scenario is that the connectivity between the nodes is intermittent and in the absence of cellular or any other networks, they may need to communicate using peer-to-peer mode. newlineAnother type of network formed by a human beings in the places like educational campus, research conference and social neighborhood, where it is assumed that communication infrastructure is not obtainable but, it needs on a temporary basis. Moreover, recent progresses in communication technologies have shown proliferation in network formed by human being carried mobile devices such as smart phone and digital gadgets, called Pocket Switched Networks (type of Delay Tolerant Network). The future conception is that human beings will communicate through smart devices, on hop to hop basis in an adhoc manner and the messages will be exchanged when they come in contact of each other in an opportunistic way. newlineThe requirements as stated above, for the provision of temporary network infrastructure would be satisfied by wireless adhoc networks. Wireless Adhoc Networks such as Mobile Adhoc Networks (MANETs) and Delay Tolerant Networks (DTNs) can be deployed on an urgent basis without need of the infrastructure, when the existing communication infrastructure is totally paralyzed or u
