“…And finally, the MMG should implement both the multicast router and the Mobile IP functionalities, which add an extra cost for Internet Service Providers. Compared to the MMG solution, which uses an implicit membership report interception and data forwarding, authors in [6] have proposed a hybrid solution based on new architectural entity called Mobile Multicast Proxy. In this solution a Multicast Proxy (MP) is a multicast router located outside the subnet of receiver or source.…”

The multiparty nature of multicast applications presents new challenges for Mobile IP users. Unfortunately, when a multicast receiver is mobile, it will experience additional delay in receiving multicast packets due to handover delay, join latency, and increased propagation delay to the new location. In this paper we propose a new solution to avoid the multicast triangle routing problem inside the home network when the Mobile IP bidirectional tunnelling approach is used. Our solution is based on the use of a new architectural entity called "Multicast Router Proxy". The proxy is used to redirect multicast traffic to the mobile receiver and avoid redundant multicast traffic passage to the Home Agent. In addition, we enhance the functionalities of the Home Agent to efficiently manage the multicast membership information for mobile receivers that are located outside the home network.

“…Some of the proactive mechanisms proposed in Refs. [41,42] to reduce the join and leave latency have been implemented in the testbed as well. As an alternative arrangement UDP Multicast Tunneling Protocol (UMTP) [43] has also been implemented to handle nonmulticast enabled networks using application layer tunnelling.…”

Streaming real-time multimedia content over the Internet is gaining momentum in the communications, entertainment, music and interactive game industries as well as in the military. In general, streaming applications include IP telephony, multimedia broadcasts and various interactive applications such as multi-party conferences, collaborations and multiplayer games. Successfully realizing such applications in a highly mobile environment, however, presents many research challenges. In order to investigate such challenges and demonstrate viable solutions, we have developed an experimental indoor and outdoor testbed laboratory. By implementing standard IETF protocols into this testbed, we have demonstrated the basic functionalities required of the mobile wireless Internet to successfully support mobile multimedia access. These requirements include signaling, registration, dynamic configuration, mobility binding, location management, Authentication Authorization and Accounting (AAA), and quality of service over a variety of radio access network (RAN) technologies (e.g. 802.11b, CDMA/GPRS). In this paper, we describe this testbed and discuss important design issues and tradeoffs. We detail the incorporation and inter-relation of a wide catalog of IETF protocols-such as SIP, SAP, SDP, RTP/RTCP/RTSP, MGCP, variants of Mobile-IP, DRCP, HMMP, PANA, and DSNP-to achieve our goals. We believe that the results and experiences obtained from this experimental testbed will advance the understanding of the pertinent deployment issues for a Mobile Wireless Internet.
