Network resources are shared as needed by a community of users. Without effective traffic controls, networks are vulnerable to possible congestion when the offered traffic exceeds the network capacity, leading to serious deterioration of network performance. Network based congestion avoidance which involves managing the queues in the network devices is an integral part of any network. Most of the networks use Drop-Tail queue management where packets are dropped on queue overflow which is global synchronization problem. This packet loss results in increased overhead in terms of energy wasted to forward a packet which was dropped, additional energy required to retransmit this packet. Active Queue Management has been a solution to the global synchronization problem and it is a very active research area in networking flows. In order to stem the increasing packet loss rates caused by an exponential increase in network traffic, researchers have been considering the deployment of active queue management algorithms. Several AQM schemes were proposed to overcome congestion by effectively managing the queues. However, there are several drawbacks in each scheme and there is a need for AQM scheme that overcome all the drawbacks and effectively manages the queue thereby avoiding congestion. In this paper an Effective queue management strategy that manages the queue proactively and simple to implement is proposed and its performance is evaluated using ns-2.
