This paper describes the design and performance of arouting protocol for mobile ad-hoc networks. Our routingprotocol is named "Hybrid Routing" in that it attempts totake advantage of both proactive and reactive approaches.The protocol is based on the concept of multipoint relaying(MPR) to minimize flooding traffic. For most applicationsover mobile ad-hoc networks, it is expected that a majorportion of communication will be done in the two-hop region.Therefore, when a node needs a route to a destinationin the two-hop region, it consults with the routing tableas the proactive approach to find the route directly. Outsidethis region, on the other hand, it discovers a route ondemand as the reactive approach through the use of MPRflooding. The proposed protocol has been validated usingthe ns network simulator with wireless and mobility extensions.The simulation results show that our MPR-HR protocolprovides higher efficiency in terms of routing overheadcompared to AODV, one of the most efficient routing protocolsreleased for mobile ad-hoc networks.
