摘要
针对无线传感器网络中数据转发存在的高耗能以及传输延时等问题,提出一种新的路由算法。相对于传统的分层路由协议在簇内采用直接数据转发,即一个簇内的成员节点直接向簇头结点转发数据。该算法结合排队理论,在综合考虑影响簇中能量消耗和端到端延迟的因素的基础上指导节点采用直接数据转发或是间接数据转发方式进行数据发送。仿真实验表明,该算法具有良好的效率和实用性。
Focusing on the problems of high energy consumption and transmission delay in WSNs caused by data forwarding,we present a new routing algorithm.Traditional hierarchical routing protocol uses direct data forwarding in cluster,that is,the members of a cluster forward the data to cluster head node directly.In contrast to this,the new one combines with the queuing theory and guides the node to transmit data in the way of directly data forwarding or indirectly data forwarding on the basis of comprehensive consideration of the factors impacting the energy consumption in cluster and the end-to-end delay.Simulation experiment shows that the algorithm has good efficiency and practicality.
