Heuristic Active Queue Management with Hazard rate function

This paper presents a heuristic packet loss approach based on Adaptive Random Early Detection (ARED) mechanism to maintain the instantaneous queue length in the buffer and estimate the packet dropping probability. The proposed scheme named as Hazard rate based Heuristic ARED (HHA) by utilizing the hazard rate function of Weibull distribution in ARED. NS2 is used to implement the simulation. Statistical evaluation is performed to show the correctness and effectiveness of the proposed scheme and simulation results. The obtained simulation results demonstrate that HHA has the best performance in contrast to ARED, Random Exponent Marking (REM) and Proportional-Integral-Derivative (PID) under both the light traffic load and the heavy traffic load in the following aspects: the packet loss rate and the instantaneous queue length.
