无线传感器网络中的多种追逃策略

         针对无线传感器网络环境下追逃游戏中追逐者和逃跑者的捕获效率和逃避效率问题，提出了几种新的追逃策略. 矢量方向逃跑法可使逃跑者有效摆脱前后夹击的不利情况，减少逃避路径的振荡.边界逃跑策略为逃跑者选择更优的逃跑方向提供可能. 智能合作追逐策略可有效发挥多个追逐者的合作效率，缩短捕获时间. 实验结果表明，矢量方向逃跑法和智能合作追逐策略均有良好表现，各种策略的组合应用具有较强的鲁棒性. 在考虑移动载体测量位置误差的情况下追逃策略仍然有效.

Abstract:

     In view of efficiency of capture and evasion in pursuit-evasion games in wireless sensor networks, several new pursuit-evasion policies are proposed. The proposed vector-ward evasion policy can bring the evader breaking away from puzzledom between two pursuers and decrease fluctuation of evasion track. The boundary evasion policy makes the evader find a better escaping direction. The intelligent collaboration pursuit policy effectively takes advantages of collaboration efficiency of multiple pursuers and reduces capture time. The results show that the vector-ward evasion policy and intelligent collaboration pursuit policy are effective. The pursuit-evasion strategies are still valid when taking into consideration localization errors of the mobile carriers.
