Handoff rerouting scheme for multimedia connections in ATM-based mobile networks

Future wireless networks promise multimedia communication and computing services for both fined and mobile users. One of the most important challenges of wireless multimedia service for mobile users is maintaining a guaranteed quality of service over end-to-end connections with multiple mobile endpoints. In this paper we describe a new handoff rerouting scheme that supports multimedia traffic in a connection-oriented mobile network, such as Mobile ATM. We analyze and compare the performance of the new scheme with respect to three related handoff rerouting schemes for connection-oriented wireless networks. The new technique shows a superior performance in route efficiency and bandwidth consumption for all traffic.
