摘　　要：针对无线智能燃气抄表物联网覆盖范围广、容量大,数据中继节点和燃气表由电池供电,能量有限的特点,提出面向无线智能燃气物联网的能量感知路由算法。采用分布式路由策略,基于网络局部信息使用贪婪选择函数进行路由规划,节省节点存储开销;将节点引力引入路径代价函数中,选取网络中剩余能量充足且距离目的节点近的邻居节点为下一跳节点。仿真结果表明,与现有路由算法相比,提出算法能量消耗更为均衡,延长网络生命期的同时没有增加路由跳数。IoT for intelligent gas metering has the characteristics of wide coverage and large capacity,in which data relay nodes and gas meters are powered by battery with limited energy.Aiming at the above characteristics,energy-aware routing algorithm of wireless IoT for intelligent gas metering was proposed.A distributed routing strategy was adopted and a greedy selection function was applied to the routing planning based on local information of the network,which saved node storage.The gravitation of node was introduced into path cost function,the neighboring node in the network with sufficient residual energy that closed to the destination node was selected as the next hop.Simulation results show that compared with the existing routing algorithms,the energy consumption of the proposed routing algorithm is more balanced,which prolongs the lifetime of the network without increasing route hops.
