There are currently two variations of mobile wireless networks Infrastructure and Infrastructure less networks. The infrastructure networks, also known as Cellular network, have fixed and wired gateways. They have fixed base stations that are connected to other base stations through wires. The transmission range of a base station constitutes a cell The network nodes in a MANET, not only act as the ordinary network nodes but also as the routers for other peer devices. The routers move freely and organize themselves randomly and the network topology may change rapidly and spontaneously also there is no centralized gateway device to monitor the traffic within network. More specifically, in our geo-routing method, the node which retains a data item first broadcasts a neighbor search message when it moves beyond d. Then, when a node receives the neighbor search message, if it is closer to the data point than the source node, it sets a waiting time for sending a reply. Because nodes closer to the data point transmit a reply message after a shorter waiting time.
