摘要
Abstract
For fair shortcomings of current existing algorithms of the Proportional Delay Differentiated(PDD) services model in the relative differentiated, the enhanced algorithm for differentiated service based on probability(WPPLQ) for the mobile location services platform is proposed. This algorithm in calculating the waiting time is optimized to make it more accurate, and by calculating the packet size to determine the service response time, so that the scheduling algorithm is more fair. By the NS-2 simulation platform, the algorithm is simulated and tested. It is verified that the PLQ algorithm and the WPPLQ algorithm are in line with performance requirements which grading the quality of service and feasibilities of differentiated service in PDD model. And it show that WPPLQ algorithm has higher fairness.关键词
