An exploratory study of congestion control techniques in Wireless Sensor Networks

摘要

Congestion is one of the pervasive issues for Wireless Sensor Networks(WSNs) because of its bounded resources with respect to data processing, storage, transmission capacity and most importantly energy supply. A multitude of survey operations have been carried out over the previous decade to investigate and address multiple congestion-oriented problems and issues that are still unresolved. Various review articles published in the literature concentrated mainly on classical techniques for congestion control such as traffic-based, resource-based, and hybrid techniques, etc. In this survey article, an attempt has been made to present a systematic review of recent efforts assisted at refining the congestion control methodologies in WSNs by considering classical approaches as well as soft computing based approaches. It is a practicable idea to take a holistic view and study both approaches together. Finally, this article discusses design difficulties, various optimization models and future directions for the mechanism of congestion control in the domain of wireless sensor networks.
