Study and analysis of congestion control parameters and its impact on transport protocol in wireless networks

Abstract

The Wireless Sensor Networks WSN can be described as a group newlineof connected wireless sensors that collect data from the environment and newlinetransmit them to a base station sink node Due to the rapid development of newlinesensors in recent years there has been a growing demand in Wireless newlineMultimedia Sensor Network WMSN applications such as video newlinesurveillance traffic monitoring and real time object tracking systems Health newlinemonitoring applications demands reliable communication with low power newlineconsumption in Wireless Body Area Networks WBAN To fulfill the quality of service prerequisites for multimedia applications a reliable transport protocol is needed One of the principle destinations of the transport layer in wireless sensor networks is congestion control The characteristics of different wireless sensor network lead to congestion occurrence that affects the performance of the network Till now congestion control procedures depend on identification of congestion and recovery yet they cannot eliminate or prevent the event of congestion The protocols for various wireless sensor networks should be designed to preserve desirable characteristics such as network self adaptation scalability fairness among competing traffic flows etc with the resource constrained nature of the underlying network The protocols should also preserve the delay and bandwidth requirements posed by application newline newline
