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.
To improve the energy efficiency and prolong the lifetime of the network is an important issue in Ad-Hoc networks.Under the premise of ensuring network connectivity, a benefit based on the non-cooperative common probable game model is proposed to reduce the energy consumption and mutual interference of nodes Function, a probabilistic game topology control model (TCOPG) is proposed to balance network connectivity and save energy consumption. A distributed algorithm is proposed to make this model converge to Nash equilibrium efficiently. Theoretical analysis and simulation results show that Compared with the existing strategies, the TCOPG topology control strategy can effectively reduce energy consumption and interference between nodes and optimize the network performance under the condition of ensuring network connectivity.
