Optimization of Handover Performance for Fmipv6
This paper presents a new protocol, namely Access Routers Tunneling Protocol (ARTP), dedicated to pre-configuring bidirectional secure tunnels among adjacent access routers before handoff. This protocol allows two tunnel endpoints to negotiate quality of service-related parameters, traffic classification aspects, security policies, such as authentication and encryption methods, buffering mechanism, etc. Once the parameters of pre-established runnels are determined, real-time traffic could be redirected in a cost-efficient way to mobile users using GRE (Generic Routing Encapsulation) tunneling technique. This protocol allows us to optimize handover performance for FMIPv6. An existing analytical model is used to evaluate the performance of the proposed handover procedure. Numerical results show that our new approach has better performance than FMIPv6 in terms of signaling cost, and the buffer size required during handoff.
