Delay-Constrained Optimized Packet Aggregation in High-Speed Wireless Ad Hoc Networks

In recent years, high-speed WLANs are introduced to service growing demand of delay-sensitive and multimedia applications. To improve efficiency at the MAC layer of high-speed WLANs, few researches have tried to utilize approaches such as Aggregation in which a number of packets concatenated into a larger frame to reduce protocol overheads. Since transmitting larger frames causes increases in delay and jitter which are crucial, especially in delay-sensitive and multimedia applications, selecting the best aggregated frame size is significant. In this paper, the authors propose an analytical model for Optimized Packet Aggregation (OPA) that finds the optimized aggregation size with regard to delay constraints of nodes.
