Congestion Handling in WSN Using

Abstract

Wireless Sensor Networks (WSNs) can create different categories of data in both Real-Time (RT) and Non-RT (NRT) practices. Due to their combinations and bandwidth restraints, such types will include controllers to alleviate the congestion using their priorities. For this reason, a Proficient Rate Control (PRC) technique has developed by using traffic type priority and virtual queue conditions. Conversely, it does not consider the problem of fair bandwidth assignment while handling the congestion in WSNs.Hence in this article, a PRC with Fair bandwidth Allocation (PRC-FBA) technique is proposed, which considers the notion of both traffic type priority and fair assignment of bandwidth. First, the challenge of bandwidth assignment in WSN has been investigated under Signal-to-Noise plus Interference Ratio (SINR) model, which intends to discover a tradeoff between fairness and network efficiency. Then, a novel bandwidth utility factor has defines concerning fairness and efficiency. And an Approximate solution in the relationship of a node using time slot assignment. Besides, the problem is formulated as non-linear programming and split into two sub-problems. So, the 2-phase technique has been introduced. In the primary phase, the relationship of the nodes has computed. In the secondary stage, time slots have been assigned to maximize the utility factor and give fair bandwidths in WSNs. At last, the simulation outcomes exhibit the effectiveness of the PRC-FBA technique compared to the conventional congestion handling techniques
