无线传感器网络节点能量的有限性限制了其大规模应用.基于地理位置信息,特别是RSSI(接收信号强度)信息的网络路由协议,可以很好地节能,但是冲突比较严重,单位能耗的数据接收量较小.基于RSSI信息对网络节点进行了区域划分,引入了CDMA技术和事件触发机制,有效的减少了冲突,从而增加了网络的寿命和数据接收量.在NS2平台上,将新协议与LEACH协议和典型的RSSI路由协议进行了仿真对比,表明了其有效性.
The limited energy of wireless sensor network node limits its large-scale application.Based on the geographical location information, especially RSSI (Received Signal Strength) information network routing protocol, can be a good energy-saving, but the more serious conflicts, the unit energy consumption data Receiving less.According to the RSSI information, the node of the network is divided into regions, the introduction of CDMA technology and event trigger mechanism, effectively reducing the conflict, thus increasing the network life and data reception.In the NS2 platform, the new protocol Compared with the LEACH protocol and the typical RSSI routing protocol, the simulation results show its effectiveness.
