Comparative evaluation of the Mobile Protocol 6 Suite

[摘要] ENGLISH ABSTRACT: Mobile IPv6 is a proposed mobility standard for Next Generation WirelessAccess Networks that allows mobile nodes, such as laptops, tablets, smartphones to stay reachable while moving around in an IPv6 Internet network.The need for MIPv6 exists because a mobile device cannot maintain the previouslyconnected link when changing location and IP address. The initial IPMobility protocol was first presented in 1993 for IPv4 and in 2004 for IPv6.The Mobile IP protocol solves the TCP/IP Stack Layer 3 mobility issue, byassigning a permanent IP Home Agent address to the mobile node. IPv4 hassome drawbacks, the main one being IP address exhaustion, making MIPv6the future option for mobility protocol in IP Networks.The main goal of themobility protocol is to enable network applications to operate continuously atthe required quality of service for both wired and wireless networks while themobile node moves around in the network.MIPv6 on its own needs optimization techniques to improve the handoverlatency of the protocol and to minimize the latency. This thesis investigatesMIPv6 simulated using OMNeT++ Network Simulator Framework and theimplementation thereof on a Linux IPv6 test bed. The test bed was used totest handover latency, overhead added by the MIPv6 extensions and packetloss. The developed test set up can also be used to evaluate different handoverschemes that might enhance the MIPv6 protocol, decreasing handover latencyand enabling real-time IPv6 applications such as Voice over IP. FMIPv6 andPMIPv6 are extensions to MIPv6 to enhance it's functionality. These protocolsare investigated and evaluated against MIPv6 in order to make recommendationson possible improvements of these mobility protocols.
