Abstract: A Wireless Multimedia Sensor Network (WMSN) is formed with a large number of distributed embedded devices equipped with camera modules. These devices are able to retrieve multimedia content from the environment and are able to extract video and audio streams, still images as well as the scalar sensor data from the multimedia content. WMSNs have generated much interest in recent years due to their huge applications such as surveillance systems, traffic control systems, environment monitoring, control of manufacturing processes in industry., Multimedia traffic produces busty high-load traffic in the network. Therefore probability of congestion in WMSNs is higher than traditional Wireless Sensor Networks (WSNs). It causes a waste of communication which reduces energy efficiency. In addition, it negatively affects reliability due to the packet losses and degrades overall performance of the network and quality of- service (QoS) of the application. To address this challenge, we propose a novel energy efficient congestion control scheme for sensor networks, called ECODA (Enhanced congestion detection and avoidance)which comprises three mechanisms: 1) Use dual buffer thresholds and weighted buffer difference for congestion detection; 2) Flexible Queue Scheduler for packets scheduling; 3) A bottleneck-node-based source sending rate control scheme.
