Comprehensive Survey Congestion Control Mechanisms in Wireless Sensor Networks:Comprehensive Survey

Abstract

Wireless sensor network (WSN) occupies the top rank of the widely used networks for gathering different type of information from different averments. WSN has nodes with limited resources so congestion can cause a critical damage to such network where it limited resources can be exhausted. Many approaches has been proposed to deal with this problem. In this paper, different proposed algorithm for congestion detection, notification, mitigation and avoidance has been listed and discussed. These algorithms has been investigated by presenting its advantages and disadvantages. This paper provides a robust background for readers and researches for wireless sensor networks congestion control approaches.

Keywords: WSN, Congestion Control, congestion mitigation, congestion detection, sink channel load, buffer load.
