A Low Latency Handoff Scheme Based on the Location and Movement Pattern

Abstract

Providing a seamless handoff and quality of service (QoS) guarantees is one of the key issues in real-time services. Several IPv6 mobility management schemes have been proposed and can provide uninterrupted service. However, these schemes either have synchronization issues or introduce signaling overhead and high packet loss rate. This paper presents a scheme that reduces the handoff latency based on the location and movement pattern of a Mobile Node (MN). An MN can detect its movement actively and forecast the handoff, which alleviates the communication cost between the MN and its Access Router (AR). Furthermore, by setting the dynamic interval in an appropriate range, the MN’s burden can also be alleviated. Finally, by performance evaluation using both theoretical analysis and computer simulations, we show that the proposed scheme can lower the handoff latency efficiently.
