摘要
无线传感器网络是监控远程环境的工具之一.由于能量和存储空间的限制,其路由协议必须维持较小的路由信息并尽可能的减少能量消耗。该论文对经典的LEACH路由算法,提出了改进,改进后的算法基于无线电传输范围和簇成员数目形成簇,同时在转发阶段引进了CSMA/CD(载波监听多路访问/冲突检测)技术以减少冲突。最后用Matlab对LEACH算法和改进后的算法进行仿真,证实改进后的算法在能量消耗上比LEACH算法有了很大提高。
Due to the limitation of power and memory size, the router protocol of wireless sensor networks must maintain small router information and reduce the power usage as much as possible.The new algorithm eonstructs clusters based on radio range and the number of cluster members.Besides, this protocol adds some mechanisms to CSMA/CD （Carrier Sense Multiple Access with Collision Detection） so as to avoid collisions. Both of the algorithms were emulated in Matlab.The result of the emulation proves that the improved algorithm is much better than LEACH in energy dissipation.
