Ad Hoc局部网络拓扑信息对能量有效拓扑控制的影响

The impact of local network topology information on energy efficient topology control in Ad Hoc network

为分析局部网络拓扑信息对网络性能的影响,基于势博弈构建了局部多功率控制模型LMTCPGT,并在该模型的基础上给出Local-MTCPGT算法,研究节点拥有局部网络拓扑信息对网络性能优化的影响。仿真实验表明,使用适当的局部网络拓扑信息比使用全局网络拓扑信息产生更高效的拓扑。

Ad Hoc network lacks centralized control mechanism to enhance the cooperation of the nodes and the node＇ s energy is limited, autonomy nodes selfishly save their own energy in running the network protocol,nodes produce a more optimized topology if they obtain more network topology information, but obtaining the network topology in- formation requires a lot of energy. This paper establishes a potential game-based Local topology control model MTCPGT, then proposes LocaI-MTCPGT algorithm, and studies the impact of having network topology informa- tion on network performance. Simulation results show that appropriate local information can produce more efficient topologies than global information.
