摘要
由于节点是随机移动的,且其电池容量有限,在无线Ad Hoc网络(自组织网络)中减少能源消耗以延长网络生存期、保证节点的安全性是研究多路径路由中的主要问题。文章分析了AODV(基于距离矢量单路径按需路由)协议和AOMDV(基于距离矢量多路径按需路由)协议的一些基本特点,在考虑安全网格定位服务的基础上,结合能源熵,提出了一种新的安全多路径路由协议-EEBSMRP。仿真计算结果表明,EEBSMRP在发现最小的节点能源消耗路由、平衡各个节点能源利用率、延长整个网络生存期以及安全性方面有较大的改进。
In view of node random movement and limited battery energy, decreasing energy penalty to prolong the network life- time and ensure node security are the main issues in the research on multipath routing in Ad Hoc networks. This paper analyzes the basic features of AODV and AOMDV protocols and proposes a novel secure multipath routing protocol, i.e. Energy Entropy-Based Secure Multipath Routing Protocol (EEBSMRP) in connection with netgrid and energy-entropy. Simulation resuits show that EEBSMRP achieves much advance in finding the routing with the minimum node energy penalty, balancing the node energy utilization rate, prolonging the network life time and improving its security.
