Best Parameter for Congestion Detection during Video Transmission in Wireless Sensor Networks

A Wireless Sensor Network (WSN) is a set of sensor nodes, whereby the nodes are equipped with multimedia devices such as cameras and microphones. Thus a WSN will have the capability to transmit multimedia data, such as still pictures, stream video, voice and monitoring data. In WSN during video transmission there is a chance of congestion occurrence. Congestion may cause multiple packet losses, which leads to the reduced quality of service (QoS) and waste of energy and increased delay. So it is very important to detect the congestion at once it occurs. So far many parameters are proposed for detecting the video congestion. In this paper we use dual queue scheduler algorithm for detecting congestion and finding the best parameter for video congestion detection. By comparing we conclude that AVERAGE DELAY is best parameter for detecting video congestion.
