Abstract
Active queue management (AQM) is the efficient way of dealing with congestion. One of the classical algorithms is random early detection (RED). In order to suit the characteristics of the wireless channal, the paper proposes an improved RED algorithm that is based on the average queue length and average packet arrival rate. Advantages in avoiding congestion compared to the classical RED algorithm are analyzed.
