摘要
为了均衡无线传感器网络中节点的能量消耗,进而达到延长网络生命周期的目的,提出一种基于最小生成树形成虚拟主干树的能量均衡的组播路由算法。该算法在选择转发节点的过程中,综合考虑前向转发区域内的节点的位置及能量信息,并引入修正因子及路径封锁技术。仿真实验表明,该算法能够有效的均衡传感器节点的能量消耗,延长网络的生命周期。
In order to balance the energy-consumption of nodes of the wireless sensor networks, and then prolonging the life-time of the wireless sensor networks, a minimum spanning tree based energy-balancing multicast routing algorithm is proposed. This algorithm considers the nodes＇ position and energy information and introduces the modifying factor and path-blocking technology when selecting the forwarding nodes. Simulation experiments show that the proposed algorithm can effectively balance the energy consumption of sensor nodes, thereby prolonging the lifetime of networks.
