Aniket M Junghare, Deepali M. Shimpi . A Survey of Congestion Control Protocols for Wireless Sensor Network. National Conference "MEDHA 2012". MEDHA, 1 (September 2012), 43-47.
Congestion occurs when too many sources are sending too much of data for network to handle. Congestion in a wirelesssensor network can cause missing packets, low energy efficiency and long delay. A sensor node may have multiple sensors like light, temperature etc. , with different transmission characteristics. Each application has differentcharacteristics and requirements in terms of transmission rate, bandwidth, delay, andpacket loss. Different types of data generated in heterogeneous wireless sensor networks have different priorities. In multi path wireless sensor networks, the data flow isforwarded in multiple paths to the sink node. It is very important to achieve weightedfairness for many WSN applications. In this paper we propose a survey of congestioncontrol mechanism in wireless sensor network. Also describe various congestion control protocol with their benefits and limitation.
