“…We have evaluated both the collaboration of SIP with MIP and the SIP-only solution for mobility management and session control. Our experiments show that, although MIP outperforms SIP for mobility management [3,14], the combination of MIP and SIP for mobility management and session control performs much worse than SIP-only mobility management. We therefore recommend using the SIP-only solution for mobility management and session control of multimedia applications.…”

“…The comparisons of the performance of the two protocols in [14] and [3] demonstrate that, in general, application-layer mobility management protocols, such as SIP, perform worse than lower-layer protocols in terms of handoff delay, signaling overhead, and transparency. However, when suitability for deployment in next-generation networks is considered, it appears that SIP is a better mobility management solution, because it obviates the need for protocol stack and infrastructure changes [3]. A number of studies indicate that the suitability of a mobility management solution depends primarily on the type of application for which it is being considered.…”

The next generation of communication networks is expected to create a heterogeneous network environment encompassing an ever‐increasing number of different access networks and end‐user terminals that will enable the introduction of and provide access to numerous feature‐rich end‐user services. It is essential that end users be able to roam from one access network to another if they are to enjoy a seamless roaming experience, which is especially important for multimedia applications such as voice, audio, and video. This paper describes how to make such a roaming experience possible in multimedia applications based on Session Initiation Protocol (SIP). It also describes several mobility management solutions and compares the suitability of SIP sessions for roaming across General Packet Radio Service (GPRS), Universal Mobile Telecommunications System (UMTS), and wireless local area network (WLAN) networks. The comparison is based on the implementation of a prototype. The advantages and disadvantages of each mobility management solution are discussed, as are the issues encountered during the implementation of the prototype. © 2004 Lucent Technologies Inc.

Future applications are envisioned to be adaptive to various changes in network, environment and situation. These so-called pervasive applications will be composed from both locally and globally available multimedia resources such as audio and video, web services and context sources. The rapidly increasing pervasiveness in todays networks, i.e. the number of mobile devices, the amount of data they generate and share (near) realtime increases rapidly. In fact this forms the basis for research efforts on the Internet of Things. The increased pervasiveness leads to numerous efficiency and scalability challenges. This chapter will detail the state of the art and binding concepts for efficient realtime sharing and mobility of multimedia and context. Additionally, it lists the associated challenges and their progress in a number of research projects.In the past decade we have seen a number of technology boosts. Multimedia like audio and video moved from analogue to digital, enabling free audio/video calls over the Internet. Multiple network types have been integrated into mobile devices and bandwidth is gradually increasing. Sensors became wireless and form wireless sensor networks for environmental monitoring, and multiple sensors are added to mobile devices enabling different interaction modalities and situation awareness, The number of mobile devices and their capabilities are gradually increasing, and server clouds have been created that offer remote processing and storage.

“…BACKGROUND TECHNOLOGIES Terminal Mobility [4] in converged networks allows devices and end-users ubiquitous access to next generation services over a pure IP multi-access platform at anytime and from anywhere. The challenges introduced by terminal mobility have only been partially addressed, mainly because the integration of mobility and converged network properties poses more stringent requirements that have not yet been fully addressed [5] [6]. In this paper we are mainly interested in the signalling effects on the integration of mobility and converged network performance at the access, core and application levels of the platform [7].…”

Abstract-Converged networks are viewed as a multi-access platform on which fixed and mobile communications can be easily merged into a unified system thus enabling the deployment of rich and personalized services. In this paper, we provide the outcomes of our research into the challenges introduced by terminal mobility in converged networks. This was achieved by carrying out performance based evaluations on various mobile network properties at the access, core and application levels of converged networks and then analysing how they affect the platform individually and as a whole. We also provide the details of our state-of-the-art experimental tests, and analyses that were carried out on emulated converged network test beds, novel architectures, recommendations and extensions which were specifically developed to improve the performance of mobile applications and services in converged networks building on key technologies such as Mobile IPv6, Session Initiation Protocol (SIP) and Peer-to-Peer (P2P) Networks.
