Abstract�� A novel routing protocol, namely adaptive forwarding cluster routing (AFCR) protocol, was proposed to improve the network scalability of a large scale mobile ad hoc network (MANET). In the AFCR protocol, nodes were divided into several 1-hop clusters by mobile clustering algorithm based on the lowest ID. With the help of clustering timer, it could quickly form cluster architecture after two rounds of control message exchange, and could form clusters simultaneously at different points in the network. Local routing information was exchanged between neighboring nodes to establish routes between cluster-heads in adjacent clusters, which were further used to propagate routing information to nonadjacent clusters to set up routes between them. Based on cluster architecture and local routing information, the proposed protocol can adaptively forward data packets between nodes. Simulation results show that compared with the destination-sequenced distance-vector (DSDV) and rapid route reconstruction DSDV (RRR-DSDV) protocols, the proposed protocol can improve network performance in the present of a large number of mobile nodes and heavy traffic load.
