如何在均衡地使用监测节点能量的同时降低监测数据的回传时延是无线传感器网络被动式路由研究中亟待解决的一个难点.综合网络传输快速性与能量均衡性需求,针对过程特征性事件,提出一种能量均衡的多流聚合路由算法(EB-MPA).该算法依据网络层次图选举区域中心节点,降低了数据到达基站的延迟.另外,EB-MPA引入能量耗损代价作为节点单跳路由选择的指标,在节点具备融合能力的情形下,进一步均衡了能量开销,延长了网络生命周期.
How to reduce the back propagation delay of monitoring data while using the energy of monitoring nodes in a balanced manner is a difficult problem to be solved urgently in the research of passive routing in wireless sensor networks.According to the requirements of network transmission fastness and energy balance, An Energy Balance Multi-Flow Aggregation Routing Algorithm (EB-MPA), which reduces the delay of data arriving at the base station according to the election of regional center nodes according to the network hierarchical graph.In addition, EB-MPA introduces the energy consumption cost as node single hop routing Of the indicators, the node has the ability to merge under the circumstances, to further balance the energy costs and extend the network life cycle.
