摘要
针对无线传感器网络的资源局限性、自组织性和网络拓扑结构的不确定性,提出了一种基于能量感知的平面路由和层次路由的混合路由协议。该协议可根据节点剩余能量的表现来判断节点的当前状态和路由选择,网络中各节点以"尽力而为"传输数据和"不得已"动态建立自适应簇头的方式进行网络通信。仿真结果比较表明:该协议具有较高簇头生成率和可靠的数据交付率,能更有效降低网络能量消耗。
In view of the limitations of resources,self-organization character and the uncertainty of network topology of wireless sensor networks,a hybrid routing protocol which is made up of planar routing and hierarchical routing based on energy-aware is proposed.The protocol can determine current state of node and routing selection according to the residual energy of the node,and each node in the network transmits data by'best effort'and network communication is carried out by'forced'dynamicly build adaptive cluster head.Simulation results show that the protocol has a higher production rate of cluster head and reliable data delivery rate,and can reduce energy consumption of network more effectively.
