把RSSI(Received Signal Strength Indication)测距技术引入到无线传感器网络的路由策略中,形成一种新型路由协议.该协议能有效减少节点能耗,从而增加了无线传感器网络的寿命.在NS2平台上,分别对LEACH协议和新型路由协议行了仿真.结果表明:新型路由协议下的网络寿命比LEACH的长;当网络工作在低负载的情况下,该新型协议的单位能耗下数据接收量比LEACH的要大.
The RSSI (Received Signal Strength Indication) ranging technology into the wireless sensor network routing strategy, the formation of a new type of routing protocol that can effectively reduce node energy consumption, thereby increasing the life of wireless sensor networks.In the NS2 platform , The LEACH protocol and the new routing protocol are simulated respectively. The results show that the network lifetime under the new routing protocol is longer than that of LEACH. When the network is working at low load, the data reception ratio per unit energy consumption of the new protocol LEACH big.
