摘　　要：针对传统ZigBee网络树路由算法存在节点能量消耗大的问题,提出了一种改进的基于能量感知和能量均衡的ZigBee网络树路由算法。该算法将邻居节点考虑在内,在确定路由的下一跳节点时,在更大的搜索范围内寻找路由开销最小的网络路径来降低功耗,同时根据路径上节点的剩余能量选择累积路径损耗和路径能量消耗较低的路径进行数据发送,从而降低了网络的总体能耗。仿真结果表明,该算法能避开能量过低的节点进行数据传输,实现了节点的能量均衡,延长了节点的生存时间。For problem of big consumption of node energy existed in traditional ZigBee network tree routing algorithm, an improved ZigBee network tree routing algorithm based on energy awareness and energy balance was proposed. The algorithm considers neighbour node, searches network path of the minimum routing in a larger search range for reducing power consumption when determining next hop node of routing. Meanwhile, it selects path of lower cumulative path loss and path energy consumption to send data according to residual energy of node on the path, so as to reduce total power consumption of the network. The simulation result shows that the algorithm can avoid low energy node for data transmission, realizes energy balance of node and extends living time of node.
