In the course of last decade, Wireless Sensor Networks (WSNs) have grabbed attention of both academic research community and industrial users. Such networks provide a broad range of applications, making them of great significance. Energy is the greatest concern of such battery-operated networks as it directly influences the lifetime of the network. As packet dropping due to congestion has a dramatically negative impact on energy consumption, congestion control is a vital issue for wireless sensor network, particularly for Wireless Multimedia Sensor Networks (WMSNs) in which bursty traffic is prevailing. In this paper, the authors present a simple yet efficient priority-aware congestion control scheme to support bursty data.
