摘要 由于大范围无线传感器网络(WSNs)节点的数量巨大,网络的能量消耗极不均,提出一种基于协作传输的分簇算法—EBBMCC—LS算法。该算法在保证网络均匀分簇的前提下,能保证网络中簇头节点的均匀分布,在簇间通信时加入协作传输策略,传感器节点之间通过协作传输构成虚拟多天线系统,改善系统性能,解决了大范围WSNs中的能耗不均现象。实验验证:该算法能够均衡大范围WSNs中的能耗,延长网络寿命,可促进大范围WSNs应用的推广。 Aiming at uneven energy consumption in large scope wireless sensor networks（ WSNs）,a clustering algorithm based on cooperative transmission technology is proposed.In this algorithm,to ensure even distribution of cluster head nodes in large scope WSNs which have even clusters,cooperative transmission technology is applied in data transmission among clusters,system performance is improved by virtual multi-antenna system which is constituted through cooperative transmission between sensor nodes,solve phenomenon of energy consurmption unbalanced in large scope WSNs,Experiment verifies that this algorithm can balance energy consumption and lengthen network lifetime,and can promote the promotion of a wide range of WSNs applications.
