Adaptive routing protocol based on OLSR for hybrid multi-hop and cellular network

Aiming at the problem of the existence of different communication mode in hybrid multi-hop and cellular network, an adaptive routing protocol based on OLSR (ACMR) is proposed in this paper. The protocol uses zone-routing technique, and maintenances the zone-routing information based on OLSR protocol. It can realize the smart choice of communication mode, agile switch and communicating with node outside by the additive control message. Simulations show the protocol can decrease the influence made by the density and mobility of node. It can improve the data packet delivery rate and average delay with small cost of routing overhead, therefore, the protocol increases the system performance and its applicability.
