摘　　要：提高能量效率以延长网络的生存时间是Ad-Hoc网络一个重要课题.在保证网络连通的前提下,以降低节点能耗和相互间的干扰为目的,基于非合作普通可能性博弈模型建立一个收益函数,设计一个均衡保障网络连通性和节约能耗的基于可能性博弈拓扑控制模型(TCOPG).并提出一种分布式算法使得此模型有效地收敛于纳什均衡.理论分析和仿真结果表明,与现有的策略相比,TCOPG拓扑控制策略在保证网络连通的条件下,可以有效的降低能耗和节点间的干扰,优化了网络性能.Prolonging the lifetime of networks by reducing the energy consumption of nodes is an important challenge in Ad-Hoc net- works. Based on the non-coorperative ordinal potential game, we propose a Topology Control based Ordinal Potential Game （TCOPG ） , which saves energy consumption and reduces interference while guaranteeing network connectivity. Further more, a dis- tributed algorithm is proposed to minimize the maximum power level. Theoretical analysis and simulation results illustrate that, com- pared with other schemes, the TCOPG can reduce the energy consumption and the mutual interference of nodes, thus optimize the performance of network.
