摘要
针对由不同功能的传感器构成的无线传感器网络,提出了一种基于权值的簇间多跳传输算法。该算法根据网络中节点能量分布的不同,引入权值因子进行簇首选举,在接下来的数据传输阶段采用了簇间多跳的传输方式。仿真结果证明该算法能够降低簇头能量消耗,均衡网络负载,从而延长网络生存时间。
For wireless sensor network composed of sensors with different functions, a multi-hop intra-cluster transmission routing algorithm based on weight-value was put forward. In this algorithm, cluster-head nodes were selected by calculating weight-value according to the different energy distribution in network nodes. In the stage of stable data transmission, the multi-hop transmission of intra-cluster was adopted. Results of simulation show that the algorithm can reduce the energy consumption of cluster-head, balance the network load and prolong the network lifetime.
