基于素数地址的动态无线传感器网络路由协议

摘要

针对分层式路由协议在建立整个网络拓扑后无法动态维护的缺点，本文修改了现有分层路由机制中节点地址的分配方法，提出素数动态路由协议。该协议利用素数乘积分解的唯一性，使得节点在网络中的位置能被明确表示出来且可以动态修改。通过仿真实验，对比常见的LEACH、SPIN和DD这3种路由协议，本文提出的D-HiPr路由协议在网络生存时间、传输时延等方面表现更优，很好地满足异构型无线传感器网络应用。%One key disadvantage identified with the hierarchical routing protocol is the lack of capacity to dynamically maintain the network topology after the establishment of an entire network topology. In this paper, a new routing protocol is proposed for short address allocation, which named dynamical hierarchical routing protocol with prime numbers. This protocol utilizes a unique decomposition product of prime numbers, and makes the networked position of the node can be represented explicitly and can be modified dynamically. The analysis of simulation results proved that, the D-HiPr routing protocol takes more advantage than LEACH, SPIN and DD routing protocols in the fields of the network survival time and the transmission delay, in addition, the D-HiPr routing protocol well meet the heterogeneous wireless sensor network applications.
