摘要
在TEEN协议中,最高级簇头与基站之间采用单跳通信方式,网络能耗较大。为了降低无线传感器网络的能量消耗,提出一种TEEN协议的节能型改进算法。该算法借鉴平面路由协议Rumor的工作机制建立簇头与基站之间的通信路径,所有簇头与基站之间都采用多跳路由方式。与TEEN协议相比,该算法明显改善了网络能量消耗和网络生存时间,并使网络规模不再受到簇头通信半径的限制。
One-hop routing is used in TEEN to establish data transfer path between first level cluster-heads and the base station, which consumes much energy of networks. In order to save energy for wireless sensor networks （WSN）, proposes an improved energy-saving algorithm （R-TEEN） based on TEEN. R-TEEN establishes data transfer path between all clusterheads and the base station based on the Rumor plane protocol and multi-hops routing algorithms. In comparison with TEEN, R-TEEN performs better in terms of energy dissipation and lifetime of networks, and eliminates the restriction of the scale of the clusterbead＇s communication range.
