| 摘 要： | 采用非合作博弈理论刻画了自私性存在条件下节点在拓扑构建过程中的相互作用，并分析了均衡拓扑的一些特征. 限制控制信息交互仅在相邻节点间进行是降低拓扑再更新频率、减少信息频繁交互的有效手段. 基于此，提出了仅依赖于相邻节点信息交互的分布式拓扑控制协议.

| Abstract: | The topology control problem is considered, creating an energy-efficient topology of wireless ad hoc networks in presence of selfish nodes. A non-cooperative game framework is established to describe the interaction of nodes in topology control process, where each node tries to transmit minimum power to preserve a connected network. Some characteristics of Nash equilibrium topologies are analyzed. A distributed topology control protocol restricted information exchange among neighboring nodes is proposed. Simulations show that the game based protocols observably eliminate the redundancy of the initial network topology. |
