摘要：In the subsequent generation of wireless networks, mobile nodes can move across heterogeneous networks and gets the best connectivity using multiple access interfaces. The network based protocol like Proxy Mobile IPv6 (PMIPv6) gives better performance when compared with the host based protocols since the serving network in PMIPv6 manages the mobility management on behalf of the mobile node (MN). The wireless Internet services are commonly accessible, when mobile nodes able to use different Internet services without any limitation. Though, if a mobile node uses different wireless networks, much limitation occurs, when they move a network different from each other. Many parameters such as packet loss, handover latency and delay affects the overall handover performance during the vertical handover process. However, there are many existing techniques to conquer, but still, it�s a challenging task. This paper enhances the functionality of PMIPv6 by introducing a multicast enabled handoff technique to improve the performance during handover with minimum delay by eliminating the false handover initiation and provide seamless handover among heterogeneous wireless networks. The obtained simulation results show a reduction in packet loss and handover latency which improves the handover performance. It also addresses the out of sequence packet problem.
