2007 (English)In: Proceedings of the 6th International Conference on Mobile and Ubiquitous Multimedia: December 12 - 14, 2007, Oulu, Finland / [ed] Timo Ojala, Red Hook, NY: Curran Associates, Inc., 2007, 6-13 p.Conference paper (Refereed)
In this paper, a proof-of-concept and a software architecture, M4 (MultiMedia Mobility Manager), is presented. In short, M4 is offering seamless mobility management to multimedia applications using a variety of wireless access networks. First, M4 is built on multihomed Mobile IP building on the principle of soft handovers. Second, network selection in M4 is based on a network layer metric combining round-trip times and jitter in round-trip times. Third, the end-user can enter its own preferences on network selection through a policy-based extension to the proposed network selection algorithm.The proposed architecture is evaluated in a live heterogeneous networking environment where handover performance is studied in detail. In addition, user-perceived quality of experience for Voice over IP using the M4 software architecture has been studied. Last, downloads of large amount of data using a combination of high and low capacity wireless networks in M4 were studied.Results indicate that the architecture as a whole and the proposed algorithms perform well. M4 can thus be seen as an implementation of the "Always Best Connected" vision.
