基于作用力模型的传感器网络簇型协议

Sensor networks clustering protocol based on force model

现有的无线传感器网络簇型算法忽视了簇头和簇成员之间的通信代价不均衡和"孤立簇头"等问题。提出了一种基于作用力模型的移动簇型协议,该协议在簇头选举时兼顾节点剩余能量和节点密度;在簇头选举后,该协议使簇头节点根据基于簇成员剩余能量和距离的作用力模型自适应移动,以均衡簇头和簇成员之间的通信代价。另外,为了实现簇头节点之间的全连通,提出了中继节点选举算法。实验结果显示:该协议能够有效地均衡网络能耗,进一步提高网络稳定性。

Existing wireless sensor networks（ WSNs） clustering algorithm neglects problems such as uneven communication cost between a cluster head and cluster members and‘isolated cluster heads＇. In view of this,a mobile clustering protocol based on force model is proposed,which considers both node residual energy and node density while cluster head is electing; in order to further balance communication cost between a cluster head and cluster members,the protocol allows cluster head node to move adaptively according to force model related to residual energy of cluster members and distances after cluster head election. Furthermore,relay node election algorithm is proposed to obtain full connection between nodes of cluster heads. Experimental results show that the protocol can effectively balance network energy consumption and further improve network stability.
