dc.description.abstractReal-time communications are likely to playa key role in the convergence of the Internet withvarious access network technologies. The Next Generation Network aims at providing thesereal-time services to nomadic users with roaming devices within the Internet infrastructure.Therefore, the objective of the study is to minimize the handover latency and packet lossduring any ongoing real-time communication by inter/intra domain mobility.Mobile IP (MIP) is a well-known network layer protocol that can support transparentmacromobility, and variants of the protocol such as Fast Handover for Mobile IP has beenproposed to provide an optimized handover scheme for micromobility within IP networks.Fast Mobile IP relies extensively on layer 2 information to anticipate a network handover andto redirect the traffic to the new location the mobile device is about to move to. However, theprotocol is burdened with triangular routing that introduces unacceptable delays for real-timecommunications. The Session Initiation Protocol (SIP) is an application layer protocol that provides different types of mobility from service to terminal mobility. Terminal mobility in SIP supports realtime communications over User Datagram Protocol (UDP). The main drawbacks in the SIP mobility framework are the call disruption delays incurred when a mobile device is in an overlapped region and the absence of mobility management on the Transport Control Protocol (TCP) connections. This project proposes an integrated mobility scheme that combines procedures of Fast Handover for Mobile IP and SIP mobility for real-time communications over UDP. An analysis of the existing protocols i.e. network layer Fast Mobile Handover for IP and SIP mobility is presented. The integrated proposed scheme efficiently aims at reducing the handover latency and packet loss for ongoing real-time conversations, i.e. Voice over IP (VoIP) call and the streaming of a video application. Simulation results presented are based on the network simulator ns-2. The simulation results compare and analyze the performance of the proposed integrated scheme to the existing protocols. Thus, the proposed architecture presents a powerful handover mobility support for Next Generation IP-based wireless systems. Recommendations for future work have been presented to further evaluate and optimize the use of the proposed integrated handover scheme.en_ZA
