MULTICASTING IN UMTS: EFFECT OF MOBILITY ON TREE MAINTAINANCE

摘要

As the concept of wireless Internet is flourishing and multicast based applications such as teleconferencing, live video broadcasts and stock quotes are targeted for its deployment, a performance modeling of multicasting in wireless domain is needed to develop efficient multicast protocols. This paper presents an analysis of the dynamics and the cost (total length) of the multicast tree in an UMTS based network. A relative cost comparison for Mobile IP based bi-directional tunnelling and remote subscription has been also presented.
