无线传感器网络的自组织成簇算法

Algorithm of self-organized clustering in wireless sensor networks

异构传感器网络是一种能量有限且分布不均衡的网络,负载均衡和能量有效是此网络路由算法的一个挑战。现提出的自组织成簇算法能够有效增加传感器网络的稳定周期,算法基于传感器节点的剩余能量和通讯能耗选择适合的簇头节点。与经典的成簇算法LEACH和SET比较,本算法能够更好实现负载均衡,并极大地提高传感器网络的稳定周期。

Heterogeneous wireless sensor networks are energy limited and imbalance networks, load balancing and energy efficiency are the most challenging task in these networks. This paper proposes a selforganized clustering arithmetic to prolong stable region of sensor network, which is based on remaining energy and communication cost to elect suitable clusterhead nodes. Compared with classical clustering arithmetic LEACH and SEP, the arithmetic can maintain load balancing of networks, and extremely prolong the stable region of network hfetime.
