Peer-to-peer real time mobility using SIP and mobile IPv6

Abstract

The problem space of this thesis is to investigate two key existing mobility support schemes namely Mobile IPv6 and Session Initiation Protocol (SIP) support for mobility which is generally known as Mobile SIP. The investigation is conducted from two perspectives. SIPsim, a minimal design and implementation of SIP as an extension to NS-2, provides thorough evaluation and clear understanding of SIP internalities and functionalities. Qualitative and quantitative analysis of both approaches reveals suitability for terminal and personal mobility respectively.This thesis contributes a novel and practical architecture i.e. On-demand Mobility Agent and Mobility Address Assignment designed with the objective to minimize the inefficiencies experienced by Mobile IPv6 and Mobile SIP by harmonizing the interaction and coexistence between both protocols. It improves the performance of Mobile IPv6 using the strength of Mobile SIP to support seamless terminal and personal mobility for both peer-to-peer and client/server communication within the wireless Internet.
