Invalidation Control for Scheduling of Data Broadcasting in Mobile Computing Environments

With the number increment of mobile computing equipment, the invalidation of equipment and broadcasting information because of wireless bandwidth, communication quality and too long scheduling queue that badly influence the system computing performance. Mobile cache is a good technology to solute this difficult problem. Considering the priority problem of broadcasting queue generated by data invalidation cache, this paper designs a multi-buffer queue-scheduling model, which classifies the priority of broadcasting data. A invalidation control strategy of data broadcasting scheduling based on mobile agent and IBM application response measurement (ARM) is presented to guarantee data executing on the terminal in the right time. The results of experiments show that the invalidation rate and average work response time of the presented model and strategy in this paper are less (20%) than the single buffer queue mode and random invalidation controlling strategy.
