Executive Summary

The IEEE 802.11 based WLAN is widely used because of its low cost and high data rate not only in a small office but also in a public hot spot. To support IP mobility of a mobile node in WLAN the mobile node should have a complicated Mobile IP function in its protocol stack if conventional host-based management protocol such as MIPv6 is used. In this paper, the authors propose an efficient hand over scheme of PMIPv6 in WLAN without changing of protocol stack in an IEEE 802.11 based mobile node. The analysis result shows that the proposed scheme reduces handover latency and number of packet lost.
