Topology control protocol based on gradient for wireless sensor network

对无线传感器网络,根据定向扩散协议提出一种基于梯度场拓扑控制算法(ETBG),以减少分级簇等级,从而达到降低时延的目的,同时采用基站移动的方法平衡网络负载,进一步提高网络的生存期。最后通过仿真验证算法的有效性。

For wireless sensor network,according to the protocol of directed diffusion,this paper introduces an energy-efficient topology control protocol based on gradient（ETBG） to reduce the level of the hierarchical clusterings,o that time delay can be reduced.At the same time,Mobile-Base-Station is used to balance the energy and the network lifetime is loaded and pro-longed.The simulation result shows the effectiveness of the method.
