An Energy Efficient Congestion Control Scheme for Multimedia Data in Wireless Sensor Networks

Abstract

Wireless sensor networks have enabled multimedia data collection such as video or audio with the advancement of computer technology. In this paper, we propose an energy efficient congestion control scheme for multimedia data in wireless sensor networks. The proposed scheme extracts and transfers dynamic regions by considering monitoring characteristics over multimedia data to reduce the transferred data. Furthermore, it can reduce the packet size by deleting and transferring low-priority bit data by considering multimedia data characteristics during congestion situations to minimize packet loss.
