摘要
无线传感器网络是一组带有无线收发装置的传感器节点组成的临时性的网络自治系统,由于无线传感器网络的节点是用有限寿命的电池来提供的,因此能量保护策略成为该网络所有协议层的关键问题。从节点级、链路级和网络级3个层次总结和评估了适用于无线传感器网络的能量保护策略;在网络层提出了基于信道接入分簇算法的路由协议,并简述了该算法的主要实现过程;通过OPNET仿真给出相关结果。
Wireless sensor networks (WSN) is a temporary receivers without the aid of any current network infrastructure. autonomous system of nodes equipped with wireless transmitters and Sensor nodes in WSN are powered by limited batteries, so energy conservation strategy is critical problem at all layer of the protocol stack. The progress of the energy conservation technologies is surveyed, and various energy conservation strategies which suit for wireless sensor networks are described and evaluated. A channel access-based cluster (CABC) arithmetic for routing protocol is introduced at last, and key simulation results are provided by OPNET.
