移动自动网中基于位置和节能的路由算法研究

综合考虑了移动自组网中投递成功率及网络连通寿命两项性能指标,提出一种基于位置和节能的路由算法,该算法根据下一跳节点所处区域的节点稠密度、下一跳节点的剩余能源、转发功耗和转发效果决定分组转发路由.讨论了实现该路由算法所需要的局部信息收集机制.最后介绍了算法的仿真实验及测试结果.实验结果表明,在能源受限的移动自组网中,所提出的路由算法在分组投递成功率和网络连通寿命方面均取得很好的效果.

RESEARCH OF A POSITION-BASED AND ENERGY-CONSERVING ROUTING IN MOBILE AD HOC NETWORKS

Taking into account both the transmission success rate and connection longevity of mobile ad hoe networks as performance indexes ,this paper proposes PBECR, a routing algorithm basing on position as well as energy conserving. PBECR forwards the packet according to the node density of next hop area, the available energy of the next hop node, the forward energy consumption and the forwarding effect. In the paper,we also demonstrated the local state information collecting mechanism. And the simulation shows that compared with position-based routing or energy-conserving routing, PBECR achieves the better performance in energy-limited mobile ad hoc networks.
