摘要
针对高空气球组网通信中干扰严重和电量供应受限的问题,提出了一种基于非合作博弈的分布式功率分配模型。通过在效用函数中增加干扰限制,保证了网络的整体信干噪比,提升了网络的通信质量;通过在效用函数中关注节点的剩余能量,使高空气球的工作时间得到延长。利用数学分析验证了模型中纳什均衡点的存在性和唯一性,并给出了纳什均衡点的求解方法。仿真结果表明,该模型可以延长高空气球的工作时间,增加网络传输的数据总量。
Strong interference and node energy-limited are big problems in aerostat networks.To solve these problems,a distributed power allocation model based on non-cooperative game is proposed.In this model,an interference penalty term is added to the utility function to improve the signal to interference plus noise ratio and communication quality of the network;moreover,the residual energy is added to the utility function to extend the survival time of aerostat network.The existence and uniqueness of the Nash equilibrium of the proposed model is proved,furthermore,the solving steps of Nash equilibrium is given.Simulation results show that the proposed model can extend the survival time of the aerostat network and increase the amount of data transferred in the network.
