摘要：

由于无线传感器网络中的节点能量有限,因此能量有效是拓扑设计时需要面对的一个重要问题,它能在很大程度上影响网络的寿命。本文提出了一种能量有效的基于簇头集的被动分簇定向扩散路由协议(HPDD)来最小化无线传感器网络中的能量消耗。该协议在被动分簇定向扩散路由协议(PCDD)的基础上加入了簇头集的概念,在网络中簇头集中每一个成员都可以作为簇头来发挥作用,从而减少洪泛建立网络拓扑结构的次数。理论分析和仿真结果都表明,该协议能有效减少网络中不必要的能量消耗,延长网络数据传输的时间,并且更适用于大中型网络。

Abstract:

Energy efficiency is a very important issue in designing the topology for a wireless sensor network which greatly affects the lifetime of the networks, since each sensor node is bounded by battery power. An energy-efficient protocol HPDD for clustering was presented to minimum energy consumption in wireless networks. This protocol introduced the notion of head-set into PCDD, and each node of the headset could work as a cluster head to reduce the number the flooding establishment of network topology. Theoretical analysis and simulation showed that the protocol could effetively reduce unecessary enegry consumption in wireless sensor networks and prolong the data transmission, which was more suitable for medium and large networks.
