基于信噪比的无线传感器网络路由选择模型

摘要

在多用户无线传感器网络中，节点在选择路由进行数据传输时，路由节点的唯利性将影响数据的通信效果，为了解决这一问题，利用博弈论的思想，在节点进行路由选择的过程中引入了竞争机制，建立了基于信噪比的路由选择模型，并求解出模型的贝叶斯纳什均衡策略，确定了路由节点的发射功率，提高了网络的通信效果。%In multi-users WSN, when a node selects routing to transmit the dates, the gainful character of routing nodes will influence the effect of communication. For solving the problem, this paper uses the idea of game theory, adds the competing protocol in selecting routing, designs the selecting routing model based on SNR, educes the Bayesian-Nash equilibrium strategy of the model, confirms the emissive power of nodes, and improves the effect of communication in network.
