Allocation of Data Items for Multi Channel Data Broadcasting in a Mobile Computing Environment

Utilising broadcast mechanism for query processing in a mobile computing environment is very much desirable due to its scalability. Therefore, it is necessary to maintain the advantage of this mechanism by minimising query access time over a large number of broadcast items. In this paper, we propose a broadcast ordering scheme at the server side, which aims to minimize query access time of mobile clients. We concern with data broadcast over multiple wireless channels. Generally, this scheme considers single and multiple data items request. We develop a simulation model to analyze the performance of the proposed scheme. The proposed scheme provides a substantially lower access time as compared to the conventional method.
