中文摘要: |
考虑融合代价所带来的影响,提出CFTC算法,综合考虑了融合代价和传输代价,将二者作为判定簇头节点的主要条件,确保选出的簇头节点执行的簇内融合都是有效的,节省了能耗;同时又考虑了节点的剩余能量且为每个参与簇头竞争的节点增加能量阈值的限制,均衡了节点的能耗负担.仿真结果表明该算法的性能优于LEACH,不仅延长了网络的生命周期,而且还降低了网络的总能量消耗. |
英文摘要: |
To consider the fusion cost, the clustering based on fusion cost and transmission cost (CFTC) algorithm which takes into account fusion and transmission cost synthetically is proposed. Both of the costs are used to determine cluster head. It makes sure that the cluster head selected can perform data fusion effectively and save energy. Meanwhile, the algorithm also considers the residual energy and sets threshold value for every candidate. So energy load among the nodes in network can be balanced. Simulation results show that the CFTC algorithm not only prolongs network lifetime but also decreases total energy consumption compared with LEACH. |
