能量高效的ZigBee网络改进路由策略

在分析现有ZigBee网络路由策略的基础上，以节省网络能耗和均衡网络负载为目的，提出一种能量高效的改进路由策略。该策略分别对ZigBee网络的簇树拓扑结构以及基于簇树算法和AODVjr算法的ZBR路由策略进行改进。改进后的路由策略在尽量减少路由开销的同时充分考虑对能量偏低节点的保护。仿真实验验证，改进策略能有效减少网络能耗，均衡网络负载，最大化网络的生存时间。

Energy Efficient Improved Routing Strategy for ZigBee Network

Based on the research of ZigBee Network’s present routing strategy, this paper proposes a routing strategy with the goal to save network’s energy cost and to balance data loading among nodes. The new strategy improves ZigBee Network’s cluster-tree topology structure and the present ZigBee Routing(ZBR) strategy which is based on cluster-tree algorithm and AODVjr algorithm. The strategy tries its best to reduce routing overhead and to protect low energy nodes at the same time. According to simulation results, it proves that strategy can effectively reduce energy cost and balance loading, successfully prolongs network’s lifetime.
