The wireless Mesh network has a broad application prospects in urban mass transit with advantages that flexible networking,a large coverage area and good mobility.This paper applied the wireless Mesh network to the mobile communication environment of urban mass transit.And it proposed a triggered by location based handover scheme and simulated to solve the handoff caused when the train moving along the track.Then,simulated networking solutions and handover scheme of this paper with OPNET.Simulation results show that the performance of Mesh network is better than that of WLAN network and the handover scheme of this paper reduced the interruption time in the handover process effectively and prevented erroneous handover or ping-pong handover.
