Congestion Control Mechanism In Wireless Sensor Network

Abstract

newline Numerous event detection and concurrent transmissions often incur high traffic demands in newlineinformation-sensing and data-forwarding environment in Wireless Sensor Networks (WSN). newlineControlling and managing the data in large amounts often remains a significant challenge in newlineresource-limited systems like WSN, by typically observing a many-to-one transmission newlinemodel. The result leads to constant buffer-over load resulting in congestion, preventing newlinedesirable performance to the level of collapsing an entire network. newlineMajor causes for congestion in wireless sensor networks WSN are its characteristics with newlinecoherent nature of traffic from sensor to base station with its many-to-one topology and newlinecollision in physical channel. Possibility of congestion into the network is when numerous newlinesensor nodes inject various sensory data. newlineInfluence of congestion is on continuous flow of data, losing the information, delay in the newlinearrival of data to the destination and unwanted consumption of significant amount of the very newlinelimited amount of energy in the nodes. The need of control congestion mechanism in wireless newlinesensor networks (WSN) for prolong system lifetime by improving fairness, high energyefficiency, newlineand improvement in quality of service (QoS). newlineCongestion control mechanism is a very important area within wireless sensor networks newline(WSN), where traffic becomes greater than the combined or individual capacity of the newlineunderlying channels. Requirement of special considerations to develop sophisticated newlinetechniques for avoiding, detecting, and resolving congestion issues in WSN. Devising newlinetechniques for achieving maximum throughput resources constrained environment of the newlineWSN needs to be considered.
