摘要: LEACH协议中最高级簇头与基站之间采用单跳通信方式,消耗能量较多。为了降低无线传感器网络的能量消耗,提出了一种基于LEACH协议的节能型分簇路由算法。该算法采用平面路由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LEACH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。

Abstract: One-hop routing is used in LEACH to establish data transfer path between first level cluster-heads and the base station, which consumes much energy. In order to save energy for wireless sensor networks (WSN), an energy-saving clustering routing algorithm(DD-LEACH) based on LEACH is proposed. DD-LEACH establishes data transfer path between all cluster-heads and the base station based on plane and multi-hop routing algorithms. In comparison with LEACH, DD-LEACH performs better in terms of energy dissipation and lifetime of networks, and eliminates the restriction of the scale of the cluster-head’s communication range.
