In the all-IP wireless networks, mobility management is a crucial issue, and it can be operated at different layers in the traditional Transmission Control Protocol/Internet Protocol (TCP/IP) stack. Session Initiation Protocol (SIP) is an application layer protocol used for the signaling and the mobility management without any modifications of the lower layer protocols, especially in the voice over IP environment. However, since it always gets the lowest priority in the networking model, it will produce the large handoff latency, the packet loss, and the handoff blocking probability. To provide an efficient mobility management, SIP can be combined with other protocols. In this paper, we propose a cross-layer mobility management scheme based on SIP and the Host Identity Protocol (HIP) which is a new protocol designed to provide secure and continuous communications between two nodes by separating the identifier and the locator roles of the traditional IP address. In the proposed scheme, the mobile node and the correspondent node use their host identity tags to establish the session connections, and the mobile nodes uses the HIP location update scheme instead of the SIP location update scheme to update its IP address when it moves to a new subnet. We discuss the proposed scheme's architecture and the major mobility procedures, including the session setup, the handoff and the location update in this paper. We also develop an analytical model to study the handoff performance of the proposed scheme, the typical SIP, and the hybrid SIP/Mobile IP, respectively. The analytical results demonstrate that the proposed scheme outperforms the typical SIP and the hybrid

“…The above mentioned literature considered only non-real time TCP traffic and did not consider real time multimedia traffic. There has been extensive work on the usage of SIP for mobility management across IP domains [7,8,16,21,26,30].

In this paper, we present a mobility management scheme for real-time multimedia sessions over heterogeneous wireless networks. Most approaches in the current literature use Mobile IP (MIP) or Session Initiation Protocol (SIP) to maintain real-time sessions during mobility. In this paper, we analyze MIP and SIP in terms of the mobility rate, packet loss and packet overheads in the user plane and propose a mechanism called PMR machanism by which the network can choose the optimum protocol for mobility management. We perform the analysis for constant bit rate (CBR) as well as for variable bit rate (VBR) traffic. We R. Rajavelsamy (B) show that for CBR traffic, the proposed PMR mechanism leads to 12-35% improvement in the system capacity, while for VBR traffic, capacity improvements ranging from about 35-50% can be obtained. Our proposed approach and the analysis are applicable to handovers between different IP domains both in homogeneous as well as in heterogeneous wireless networks.

The Session Initiation Protocol (SIP) is the preferred signaling protocol for creating and terminating multimedia sessions in an IP network. Also, voice over IP is becoming the favored means of voice communication mainly because of its low cost when compared to voice communication over traditional networks like cellular and PSTN. Therefore, seamless transfer of calls or handoff between the traditional and IP networks becomes important.We describe a technique to achieve seamless mid-call handoffs in a scenario where a handoff occurs between the cellular network and the IP network. The technique we describe makes use of a network element acting as an ISDN gateway, SIP conference server and SIP proxy server. We have measured handoff delays from IP to ISDN network and vice-versa. When using the proposed soft handoff technique, these delays are 0.10 s and 0.02 s, respectively. Finally, we share the results and some of the challenges we faced while implementing the overall mechanism on a dual-mode handset.
