To solve the problem of insufficient power for wireless sensor networks, a data transmission model based on game theory is proposed, in which nodes participate in the game and potential residual energy of the relay node, a parent-child node loss as well as the communication link between the game results to upstream communication link caused by overhead and other factors are included in the profit function. The quality of their game results is comprehensively measured,a balance point in multi-constraints condition is established. This model is compared with end-end time delay, data efficiency and energy consumption of AODV protocol, combined with NS-2 simulation software,and the results indicate that the model is on the premise of ensuring the quality with energy savings compared with AODV protocol.%针对农业应用中无线传感器网络电源续航能力不足的问题,提出一种基于博弈论的数据传输模型,该模型中,将参与博弈的节点和潜在中继节点的剩余能量、父子节点间通信链路损耗和此次博弈结果对上游通信链路造成的额外开销等因素纳入效益函数中,从而综合衡量博弈结果的优劣,建立一种多约束条件下的均衡点.结合NS-2仿真软件将本模型与AODV协议的端端延时、数据效率和能量损耗对比,并通过实验结果表明:该模型与AODV协议相比,可以在保证通信质量的前提下节约能量.
