An Explore to Congestion Control in Wireless Sensor Network
Wireless Sensor Network (WSN) is the terminology which is stated as the collection of sensor nodes which are having a wireless linking between them. Wireless sensor network gives birth to the term congestion which can be expressed as the traffic jam in the network. There are various sources and causes of traffic jam i.e. congestion in network. To avoid such traffic jam various policies and techniques are implemented. Protocols named as PSFQ (Pump Slowly Fetch Quickly) and CODA (Congestion Detection and Avoidance) is used widely in WSN to reduce the congestion problem. Protocols increase the data rate & improve the channel efficiency. Thus there are certain congestion control techniques available in WSN.
