Abstract
Buffer sizing is an important network configuration parameter that impacts the Quality of Service (QoS) characteristics
of data traffic. With falling memory costs and the fallacy
that 'more is better', network devices are being overprovisioned with large bu ers. This may increase queueing delays
experienced by a packet and subsequently impact stability
of core protocols such as TCP. The problem has been studied extensively for wired networks. However, there is little
work addressing the unique challenges of wireless environment such as time-varying channel capacity, variable packet
inter-service time, and packet aggregation, among others.
In this paper we discuss these challenges, classify the current state-of-the-art solutions, discuss their limitations, and
provide directions for future research in the area.
