基于光晕网络模型的平衡负载的数据传输算法

Coronas-based network model load balanced data gathering algorithm

无线传感网络的数据传输消耗了节点的大部分能量,为此,提出基于光晕网络模型的平衡负载的数据传输(coronas-based network model load balanced data gathering,CLBDG)算法,降低能耗。建立光晕网络模型,推导每个光晕内所需的节点数;利用每个光晕建立数据传输路径,降低路径跳数和平衡节点间的负载;在保证覆盖区域的同时,通过控制节点数限定数据包数,控制网络负载。实验数据表明,CLBDG算法能够有效控制、平衡负载,节省了节点能量,提高了网络寿命。

In wireless sensor network(WSNs),most of the energy of the sensor nodes is depleted in the process of data communication,to improve the energy utilization.Therefore,coronas-based network model load balanced data gathering(CLBDG)algorithm was proposed.Coronas-network model was constructed,and the number of nodes in each coronas was induced.The path of data gathering consisted of coronas,to reduce the hop count and balance the load between nodes.While satisfying the coverage requirement,data packets were generated according to a limited number of nodes sufficient to cover the area.Experimental results show that the CLBDG brings huge enhancement in network lifetime by limiting and balancing load.
