In many traditional On Demand routingalgorithms in Ad hoc wireless networks, a simple flooding mechanism is used tobroadcast route request RREQ packets when there is a need to establish aroute from a source node to a destination node. The broadcast of RREQ may leadto high channel contention, high packet collisions, and thus high delay toestablish the routes, especially with high density networks. Ad hoc on DemandDistance Vector Routing Protocol AODV is one among the most effectiveReactive Routing Protocols in MANETs which use simple flooding mechanism tobroadcast the RREQ. It is also used in Wireless Sensor Networks WSN and inVehicular Ad hoc Networks VANET. This paper proposes a new modified AODVrouting protocol EGBB-AODV where the RREQ mechanism is using a grid basedbroadcast EGBB which reduces considerably the number of rebroadcast of RREQpackets, and hence improves the performance of the routing protocol. Wedeveloped a simulation model based on NS2 simulator to measure the performanceof EGBB-AODV and compare the results to the original AODV and a position-awareimproved counter-based algorithm PCB-AODV. The simulation experiments thatEGBB-AODV outperforms AODV and PCB-AODV in terms of end-to-end delay, deliveryratio and power consumption, under different traffic load, and network densityconditions.
