A Novel Frame Aggregation Scheduler to Solve the Head-of-Line Blocking Problem for Real-Time UDP Traffic in Aggregation-Enabled WLANs

摘要

In this letter, a novel frame aggregation scheduler is proposed to solve the head-of-line blocking problem for real-time user datagram protocol (UDP) traffic in error-prone and aggregation-enabled wireless local area networks (WLANs). The key to the proposed scheduler is to break the restriction of in-order delivery over the WLAN. The simulation results show that the proposed scheduler can achieve high UDP goodput and low delay compared to the conventional scheduler.
