Survey on Congestion Control Mechanisms for Wireless Sensor Networks

A survey on recent congestion control schemes in wireless sensor network

“…In [3], an overview of congestion control techniques for constrained environment is made and an idea of improving the mechanism of CoAP is proposed to address the need of resource constrained nodes (e.g., 8-bit microcontrollers with only a small RAM and ROM) with weak network connection (e.g., 6LoWPAN with speed of 250 kbps). CoAP protocol is the implementation of REST architecture which is delivered by compressing HTTP.…”

A Critical Insight into Congestion Control Mechanism in WSN

“…Some of studies [12] asked about on this issue with support of numerical results while some of researchers [20,22] have analyzed and provide specific solutions of the problem. The paper [21] emphasizes on congestion control techniques in some constrained environment by improving Constrained Application Protocol while [9,11] reviews a number of congestion control protocols, algorithms and able to compare the congestion control algorithms, congestion avoidance algorithms and reliable data transport mechanisms. The future directions relevant to different applications were also been discussed with focus on performance driven and controlled mechanism.…”

Congestion Reduction Using a MAC Scheduling Mechanism in a Wireless Sensor Network

“…Constraint (2) states that each group has a minimum size. Constraints (3), (4), (5) and (6) are both equal to one, which requires several constraints to be modeled using ILP (see [19] for a modeling of the product of two binary variables). Constraint (7) states that the path from a direct child of sink to sink cannot be broken, as sink is always active (i.e., in all groups).…”

“…This paper aims to reduce the congestion in the network (see [6] for a survey on congestion reduction for WSNs). Our protocol activates groups of nodes at different periods.…”
