摘要
微机电系统、处理器、无线电通信以及存储技术的进步促进了无线传感网络飞速发展。为适应无线传感网络设计的特殊要求,其网络协议发展的重要性越来越突出。首先简述3种协议———LEACH、SPIN和定向扩散,然后详细介绍一种高能效定期数据更新协议SAFE,利用含有公共信息的多个汇节点数据共享,实现在发送路径中节省能量,最后对4种协议进行比较。
Recent advances in MEMS （ micro - electromechanical systems）, processor, radio, and memory technologies have dramatically enabled development of wireless sensor networks. Three protocols - - LEACH, SPIN and Directed Diffusion are introduced. An efficient information dissemination protocol to update periodic data in WSN, called SAFE （Sinks Accessing data From Environments）. This protocol attempts to save energy through data delivery path sharing among multiple sinks that have common interests.
