Abstract :
This paper proposes a user-oriented handoff system architecture to solve the detection and collection of mobile user locations using wireless sensor network (WSNs) and location-aware technologies. The proposed user-oriented seamless handoff (USH) system adopts two seamless handoff control schemes: proactive buffering (PB) as well as double queue (DQ), to minimize handoff delay and solve the packet out-of-order problem when the network traffic situation is not stable. SUH system effectively achieves seamless user-level handoff and guarantees quality of communication during handoff
