Abstract:
This paper proposes a ZIPF-based scheduling algorithm to solve the too long broadcast cycle which lead to very long access time in skewed access mode multi-channel broadcasting environment.By reducing the average time of hot times to reduce the average access time,in order to further optimize the average access time,each channel uses the log-time algorithm for scheduling data items.Experimental results show that the algorithm effectively reduces the user's average access time,and improves the capability of data broadcast efficiently,especially in skewed access mode.
