Component-based Multirate Image Transmission over Wireless Sensor Networks

Image sensors´ digital transmissions are significant challenge to the wireless sensor networks (WSN) due to resource constraints. In this paper, we propose a novel position-value (P-V) oriented multirate image transmissions approach called image component multirate transmissions (ICMT) over WSN. This method adapts different reliable levels of transmissions to various P-V segmented components within the compressed image bit stream. Simulation results show that the proposed scheme achieves high energy efficiency in WSN while enhancing the image transmission quality.
