Energy-aware on-line algorithms for image transmission over wireless LAN

In this paper, we analyze the performance of on-line image transmission algorithms designed to minimize wastage of battery energy and bandwidth over bursty wireless channels. These algorithms estimate the wireless channel state in an online fashion and adapt accordingly. Theoretical basis for these algorithms are presented using competitive analysis. Computational and transmission energy consumption factors are taken into account. Experimental results show that some of the proposed algorithms can result in significant performance improvement.
