摘　　要：从网络拓扑结构连通性与网络整体同步行为的内在关联出发,提出一种移动智能体网络的功率控制策略.首先确定满足网络拓扑结构连通的最小感知半径;其次以提高整个移动智能体网络的拓扑结构抗毁性为优化目标提出一种代价函数,在最大功率限制下的最大感知半径及保证连通的最小感知半径的范围内采用粒子群优化算法(PSO)予以优化,寻求同时满足网络连通性与抗毁性需求的个体感知半径;随后基于该控制策略,以个体感知邻域内运动方向偏差最大的2个邻居个体运动方向的中值作为个体下一时刻的运动方向,研究了移动智能体网络的快速同步问题.仿真结果表明:通过调节个体感知半径,移动智能体网络的功率控制和抗毁性能得到了提高.A new strategy of power control in mobile agent networks was proposed according to the in- ner relationship between connectivity and the synchronization in network topology. Firstly, the minimum radius keeping the networks in connect was calculated. Then a cost function aims was put forward to improve the invulnerability in the topological structure of mobile agent network, and the function was optimized by particle swarm optimization （PSO） algorithm in the scope of maximum limited by power and the minimum kept connected to find the best radius which satisfies the connectivity and invulnerability. Based on the strategy, the fast synchronization by the new rule was studied. The result shows that the power control and invulnerability are improved by optimizing the radius.
