In this paper, the performance of JPEG image compression and transmission using TinyOS-based Imote2 wireless sensor network platform is experimentally evaluated via a newly developed testbed. This testbed supports multihop sensor networks based on the Imote2 platform equipped with the Imote2 Multimedia Sensor Board. In addition, a standard JPEG library is embedded into the Imote2 platform to provide in-node image compression. The processing and transmission times, power consumption, and peak-signal-to-noise ratio performance metrics measurements are reported. The results show that the processing requirements are less than those of the transmission. According to the results, a tradeoff between the image quality and the energy and delay costs may be obtained.
