Jigang Wen · Journal of Chinese Computer Systems · 2013
Cooperative routing is a cross-layer routing design scheme which combines the physical layer cooperative communication technology and the network layer routing technology to improve network performance.However,the existing cooperative routing mechanism doesn't make good use of the characteristics of network topology and can hardly achieve optimal cooperative routing performance.Based on node distribution of the wireless multi-hop network,this paper proposes a cluster cooperative routing algorithm to improve the transmission reliability.The algorithm includes three phases: the phase of cluster formation,the phase of routing between clusters and the phase of routing in the cluster.To utilize the broadcast characteristics of wireless transmission and cooperative ability of neighbor nodes in wireless networks,each phase in the algorithm takes the impact of node distribution on cooperative communication into consideration to optimize the algorithm design.Simulation results show that the proposed algorithm can significantly reduce the outage probability of the route,increase the reliability of the network.
