Congestion control in mobile ad-hoc networks using Intelligent Priority Queueing Scheme

M. Rajeswari, Dr. N. Kasiviswanath

Congestion control in mobile ad-hoc networks (MANET) is an area of interest in networking which has got a noticeable attention by researchers during the recent years. There exist different mechanismsfor providing a solution to congestion problem in MANETs, each of which concentrates on one or more key parameters of MANET such as Load, Remaining Energy, Signal Strength, Priority Queueing etc. to achieve the goal.  Different proposals were made by various researchers with an intention of providing ananswer to the problem.  However, based on the design approach, each of those methods carry their own set of pros and cons.  In this paper, we propose a unique methodology to reduce congestion in MANET using a very intelligent queueing scheme that achieves an efficient usage of the limited network resources at the node.  This mechanism can be further combined with various existing routing protocols to achieve a significant performance in mobile ad-hoc networking while attaining the core objective.  As the proposed method operates at a very basic level of routing, it can be adopted easily byvarious existing congestion control protocols.
