Handoff mechanism in MPLS enabled wireless network

摘要

In this paper, we propose a layered MPLS based mobility solution to support mobility in seamless manner. This scheme uses an enhanced type of MPLS router called label edge mobility agent (LEMA), takes an active part in mobility management. To support fast and dynamic handoff an intelligent multicasting method is discussed that shows good performance in handoff latency and packet loss. The analytical results show a remarkable network performance in terms of reducing location update, handoff delay, packet loss and buffer size. We compare our result with other MIP based protocols like MIPv4 and H-MPLS.
