摘要: 在无线传感器网络中,数据的传递策略对网络的能量损耗具有重要的影响,为此,提出了一个基于贝叶斯博弈的数据传递模型。在该模型中网络节点为了获取最大的收益,在考虑自身能量水平的基础上,适当的调整发送/转发的数据量。当节点发送/转发的数据满足一定条件时,网络存在均衡状态。仿真结果表明,该基于博弈论的数据传递策略在均衡状态下能够明显降低能量损耗,延长网络的使用寿命。

Abstract: In Wireless Sensor Networks(WSNs),data transfer makes a great impact on energy consumption.Therefore,a Bayesian game model is proposed,in which the nodes,considering the energy level of themselves,may get maximum payoff through adjusting the quantity of data to be sent or forwarded.When the data,sent or forwarded,content some condition,there has Nash equilibrium in wireless sensor networks.The computational results demonstrate that the game model in Nash equilibrium can decrease the energy consumption and prolong the life of wireless sensor networks.
