Congestion Control using Adaptive Buffer Flow Managements in WSN

Congestion in wireless sensor networks usually occurs when the traffic is heavy, so performance of the networks depends to a great extent on how well internet works. The WSNs consists of unbelievable network load and it leads to energy wastage and packet loss. This paper presents a survey of various congestion control proposals that preserve the original Node -to-Node idea of TCP by neither sender nor receiver relies on any explicit notification from the network and buffer flow management determines how to drop or buffer the arriving packet when congestion occurs. This paper focus on a many problems, starting with the basic problem of eliminating the phenomenon of congestion collapse, and include the problems of effectively using the available network resources in different types of environments. Many other techniques have the ability to measure the loss rate, delay and bottleneck buffer size, and level of congestion in wireless sensor networks.
