A Neighbor Knowledge with Zonal Routing Protocol to Reducing Routing Overhead in

ABSTRACT — In mobile ad hoc networks the nodes will be in a mobile state so there may be a frequent link breakages which leads to frequent path failures and route discoveries. Sending periodical message causes overhead. Reactive Routing protocol causes less overhead when compared to Proactive routing protocol. In the existing system they used neighbor coverage based probabilistic rebroadcast protocol(NCPR) for reducing routing overheads in MANETs. We used SBA and NCPR for finding routes. Since NCPR is a reactive routing protocol latency time will be higher, so we are combining the hybrid routing protocol (ZRP) along with NCPR to reduce the latency time. In our proposed system since both proactive and reactive concept are there it perform better for finding paths and the simulation result shows that the latency time is reduced.
