Handover Performance Analysis in Mobile IPv6 - A Contribution to Fast Detection Movement

Nowadays, mobile communications face new challenges in its evolution: The convergence of wireless cellular networking and TCP/IP architecture. In addition, Internet protocols do not support mobility, so different mechanisms to offer seamless mobility have been proposed. The fourth generation (4G) IP-based wireless networks have lead IP level the ideal candidate where mobility should be implemented. Mobile IP is the protocol proposed for mobility management at the IP layer. Handover management is one of the most critical phases of this protocol. The high delay of this phase is a limitation to seamless mobility. In this work a detailed analysis about handover process is presented. Moreover, movement detection is a very costly stage in handover mechanism so a new fast movement detection algorithm to improve this detection has been developed. It is called FDML3 (Fast Detection Movement Layer 3). As the handover analysis as the algorithm proposed has been carried out thanks to OMNeT++ simulator.
