摘要
无线传感器网络是由大量低功耗的传感器组成.由于无线传感器的能量有限,所以如何延长传感器网络寿命成为设计路由协议的关键问题.为此,分析了无线传感器的簇类路由协议LEACH协议和LEACH-C协议,针对它们存在的缺陷,提出一种新的路由协议LEACH-NEW协议,该路由协议改变原协议的一跳路由为多跳路由,并用仿真软件NS2对3个协议进行仿真比较.由仿真结果可以看出,LEACH-NEW协议较其它2种协议显著地提高了网络寿命.
In wireless sensor networks that consist of a large number of low-power sensors. Because the sensor＇ s energy is limited,one of the main design is to obtain long system lifetime. The authors firstly analyse LEACH and LEACH- C clustering routing for wireless sensor networks. Aimming at their shortcoming, they present a new routing LEACH-NEW. This routing uses muhi-ho Pinstead of one hop. At last ,they use NS2 to simulate them. Simulation show results that new routing exhibits noticeably longer system lifetime than rouing LEACH and LEACH-C.
