针对无线传感器网络中耗能不均问题，以及可再生能源节点在农田无线传感器网络中应用的具体情况，将博弈理论引入无线传感器网络能耗问题研究中，建立了基于博弈理论的节点成簇方法，实现提高可再生能源利用率、均衡非可再生能源节点能耗的目标。方法首先建立簇收益与簇内节点收益评估模型，进行簇收益计算、簇内的两类能量异构节点个体收益的计算。在计算簇收益和节点收益的基础上进行节点成簇博弈，使得成簇方案向收益更高的策略空间进行跳转，最终达到博弈中的均衡状态。仿真实验表明，通过博弈进行无线传感器网络成簇，能够充分利用可再生能源节点能量，降低和均衡非可再生能源节点能耗，最终达到延长网络寿命的目标。

Farmland Wireless sensor networks have the problem of uneven energy consumption. And with the intro?duction of renewable energy nodes,the farmland wireless sensor networks need a more rational energy collaboration strategy among energy heterogeneous nodes. The Game Theory was introduced in this paper to deal with the collab?orative energy utilization problem in the energy heterogeneous network,and ultimately to achieve the goal of renew?able energy utilization improving and non-renewable energy consumption balance. This method established cluster and cluster nodes payoff assessment model for cluster payoff calculation,as well as payoff calculation of cluster nodes with different energy types. On the basis of payoff calculation,nodes clustered by game theory. Nodes jump to cluster strategy spaces with higher payoff,and at last get the game equilibrium. The simulation result shows that wireless sensor network clustering by game theory can take full advantage of renewable energy node energy and bal?ance the energy consumption of non-renewable energy nodes,therefore to extend the network lifetime.
