Abstract
Based on the concept of contention reservation for polling transmission and collision prevention strategy for collision resolution, a fair on-demand access (FODA) protocol for mobile ad hoc networks (MANET) is proposed. In the protocol, a clustering network architecture acquired by clustering algorithm and reserving channel resources by fair collision prevention (FCP) algorithm to obtain polling service are adopted, so that the hidden terminals (HT) and exposed terminals (ET) problems existed in traffic transmission due to carrier sensing, multihop architecture and wireless transmission method can be completely eliminated. In addition, the FCP algorithm can also completely resolve unfair phenomena and access collisions in the present of contention access of newly active nodes. Finally, performance comparison of the FODA protocol with carrier sense multiple access with collision avoidance (CSMA/CA) and polling protocols are presented and simulation results show that the proposed protocol can achieve higher throughput, lower average message dropping rate and delay.
