QoS-AWARE HANDOVER SCHEME USING CONTEXT TRANSFER WITH LINK LAYER TRIGGER FOR HIERARCHICAL MOBILE IP

摘要

The tremendous rate at which the Internet is growing has driven various networks to converge into a fully unified IP based architecture. The challenge in such a complex network is to provide a seamless support. This paper describes a QoS aware handover scheme based on the Hierarchical Mobile IPv6 architecture. Here enhancements to the scheme to improve seamless support were investigated. The two main elements added to the scheme are the use of link layer trigger and also context transfer. The results show that the performance for the average handover delay has increased by approximately 76% for the proposed scheme.
