Abstract
The quality of service in Wireless Multimedia Sensor Networks (WMSN) is related to packet loss rate. Recently different studies have been done on developing efficient protocols in the transport layer for controlling packet loss in WMSN. However, all of these protocols are independent of the characteristics of multimedia content. Transport layer for wireless sensor networks have many challenges. One of these challenges is the congestion. It leads to undesirable effects such as increased the packet delay, energy consumption and decrease quality of video. Considering these effects provide appropriate congestion control mechanisms can lead to improve the quality of service (QoS) requirements. This paper introduces a new congestion control method for transmitting the video stream. This method gives the faster congestion detection and congestion control based on the property of video information. The experimental results shows that our method provide performance improvement in terms of high video quality, packet loss, energy conservation and delay compared to other protocols.
