摘　　要：因为移动P2P网络具有动态性而且移动节点能量受限,提升移动P2P数据传输效率至关重要。利用蚁群优化算法,将蚂蚁的信息素与节点的能量和通信带宽结合起来,在蚁群选择路径时,减少其寻优路径上的信息素浓度,根据概率路由表中信息素的浓度对路由选择策略进行调整,避免网络拥塞和个别节点能量消耗过快,提出了一种移动P2P网络的多路径路由选择算法。实验结果表明,与EDSR路由协议相比,提出的算法能够降低节点的分组丢失率和端到端的平均时延,提高了网络的生存周期。For the dynamic of P2P network and the limited energy of the mobile node, enhancing the mobile P2P data transmission efficiency is essential. By using ant colony optimization algorithm the ant pheromones were combined with the node energy and communication bandwidth. When ACO selected the path, the concentration of the pheromone on its optimization path was reduced. The routing selection strategy was adaptively adjusted by the pheromone density of routing probability table in order to avoid network congestion and excessive energy consumption of individual nodes. A muhipath routing selection algorithm in mobile P2P network was proposed. Experiment results show that the proposed algorithm can reduce packet loss rate and the average delay compared with EDSR routing protocol, prolonging the lifecycle of the whole network.
