Abstract: At the time of Disaster, the towers get collapse leading to loss of Network. Hence we need to communicate with people lying in Debris becomes essentially important to save them. Hence we want to use D2D Technology for our device to device communication where network availability is absent. This Region without Network is made to interoperate with the Region Having Network connectivity with the existing Protocol by developing Gateway at the interface of the two regions one with Network availability and other with Network absent.
