Pursuit-Evasion Policies in Wireless Sensor Networks

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.
