A Mobile Ad-hoc Network(MANET) is a wireless communication network where the nodes are not within the direct transmission range.Hence intermediate nodes are required to forward data.Oppertunistic data forwarding can?t be used in MANETs since the lack of an effective routing protocol. In this paper, a novel routing protocol is designed to use opportunistic data forwarding in MANETs with beacon-less nearest neighbor query processing method for reducing traffic and maintaining high accuracy of the query result in mobile ad hoc networks.In these methods, the query-issuing node first forwards a query using geo-routing to the nearest node from the point specified by the query (query point). Then, the nearest node from the query point forwards the query to other nodes close to the query point, and each node receiving the query replies with the information on itself. The protocol which has superior performance compared to other routing protocol such as link state (LS)-based routing, DV-based protocols and reactive source routing.Such a routing protocol is known as PSR(Proactive Source Routing) protocol.PSR protocol has less overhead than the baseline protocols. The simulation is done by ns2.
