|Title||Cluster Based Geo-Routing Protocol|
This paper addresses the problem of the overhead resulting from flooding the control packets in mobile ad hoc networks in searching for routes between the source and destination. We propose a location enhanced routing protocol for clustered MANETs based on the cluster based routing protocol (CBRP). Our protocol employs local position information obtained by smart antennas to discover routes and make routing decisions for the clustered MANETs. One of the CHs, named general manager (GM), is assigned the responsibility to maintain the local positions of the other nodes. The GM divides the space into four quarters and periodically sends HELLO messages that reach all the nodes. Then each node sends its location information to the GM when this information is changed. Also, the GM has the responsibility to route data from the source to the destination. Simulation results show enhancing the performance of clustered MANETs by decreasing the control packets overhead.
