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.
