Abstract

Abundant information in the Grid is being delivered to enormous destinations among which the mobile users maybe the mainstream in near future. Accordingly, the bottleneck exists at the last mile from the Grid backbone to those mobile terminals where wireless environment places limitations on the rate and amount of communication. Point-to-multipoint (PTM) communication is an effective solution to this limitation. This paper develops the PTM parallel channels content organization mechanism to support timely and reliable access to the common interested information on the Mobile Grid, which has great practical value in the mobile IPTV application scenario. Moreover, we systemically study the parallel channels content organization for non-concurrent and concurrent content retrieval, and then contribute better content organization and retrieving algorithms which fully utilized the concurrent parallel content retrieval capability. The algorithms proposed could deliver information in a very high-performance way to larger user groups so as to achieve shorter response time and less network latency, both for the source-side and for the destination-side. We demonstrate the effectiveness of related mechanisms using a number of examples and some performance experiments.
