【摘要】 由于传感器网络节点采用电池供电,单个节点能量的过度消耗会导致网络的失效,因此传感器节点可能因为能量限制而拒绝转发数据.正是因为传感器节点存在这种潜在的自私行为,传感器网络路由问题可以描述为一个减少节点能量消耗而获得最大网络效益的博弈问题.文中提出了一种无线多媒体传感器网络QoS路由博弈模型,并证明了纳什均衡的存在性.同时,给出了一种基于混合纳什均衡的无线多媒体传感器网络QoS路由算法.更多还原

【Abstract】 Because of the sensor node of wireless sensor networks using batteries to supply the power,so the sensor node would refuse to forward the packet when its energy is limit.The routing problem of wireless sensor network can regard as game problem because of the potential selfish action.In this paper,a model of routing game for wireless multimedia sensor networks is present,the equilibrium of the routing game is discussed,and a game routing algorithm for wireless multimedia sensor networks is given.更多还原
