Wireless Sensor Network Energy Balancing Routing Algorithm Based on Game Theory

针对无线传感器网络节点能耗不均匀,容易形成网络分区的问题,提出了一种基于博弈论的无线传感网络路由选择策略,建立传感器节点之间以剩余能量为效用的博弈模型,求解并确定节点剩余能量最优的路由。仿真结果表明,所提出的路由选择策略可以有效地最大化节点的剩余能量,同时当该模型处于纳什均衡解时,每条路径的能耗处于均衡状态,有效地利用了传感器节点的能量资源,避免了网络能量的空洞,延长了网络的生命周期。

Uneven energy consumption for wireless sensor network node will easily result in the problem of network partition, for which, a routing strategy based on game theory was proposed. Firstly, a game model between the sensor nodes with the residual energy as the utility was established, and then by solving the model, the optimal routing of the nodes＇ remaining energy was ultimately determined. Simulation results show that the routing selection strategy can effectively maximize the nodes＇ residual energy, and when the model is in Nash equilibrium, the energy consumption of each path is in equilibrium. So the energy resources of the sensor nodes can be efficiently used, avoiding the emptiness of network energy and prolonging the network lifetime.
