A Proxy-Based Fast Handover Scheme in Mobile WiMAX Networks

Hwa-Sub Lee,Bok-Ki Kim,Sang-Won Min

Abstract

In this paper, we propose a proxy-based fast handover scheme to improve a performance in the mobile WiMAX network using PMIPv6 for supporting the network-layer mobility. In our proposed scheme, we define three link-layer messages and one network-layer message to reduce the handover latency, and propose a buffering mechanism to minimize packet loss and solve out-of-sequence problem. A performance evaluation indicates that the proposed scheme works more efficiently than PMIPv6 in terms of the handover latency and packet loss.
