Effective Impact of ECN with RED to Control Heavy Congestion

A Mobile ad-hoc network (MANET) is a self configuring infrastructure less network of mobile devices connected by wireless links. In MANET the proper maintenance of resources and link to avoid congestion is main issues. In this paper our motive is to get better utilization of resources and avoid congestion. For communication system uses queuing techniques, Traditional queuing techniques like Drop tail has been defeated due to their limitations. Therefore we use AQM i.e., RED queue, our focus is to illustrate the strong constrain for entry of packets in queue buffer. In contrast pure RED also has bugs like it does not accommodate Quality of service (QoS). Considering this we use RED with ECN (Explicit Congestion Notification) which marks the packets instead of dropping, it prevents from tremendous packets dropping and overcome from the drawbacks of traditional methods.
