A new invalidation control strategy for scheduling of data broadcasting
QI Xinyan · Sciencepaper Online · 2009
Increasing with the number of mobile computing equipments, the system computing performance are seriously influenced because of the invalidation of equipment and invalidation broadcasting information which is induced by wireless bandwidth, communication quality and too long scheduling queue. Mobile cache is a suitable technology to solute this 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.
