Dual Transmission Architecture for Mobile Multicasting
With the popularity of mobile devices, Internet service providers are interested in supporting mobile applications. Mobile IP standards have been developed without considering multicast services. This paper explores the issues of multicasting for mobile hosts and problems of previous approaches, and proposes dual-transmission architecture for mobile multicasting (DTAMM), which provides reliable and optimal multicast communication in mobile environments. Proposed architecture is based on the standard protocols and, with some functional extensions to network components, solves most of the problems currently identified. We also developed a simple cost-analytic model to evaluate its performance.
