Abstract :
Video communications using mobile wireless devices is a challenging task due to the limited capacity of batteries. Some of the key technologies that affect battery life are source compression, channel error control coding and radio transmission. In this paper, we propose several experimental profiling based mathematical models for energy consumption of MPEG4 video transmission. These models capture both the computational and transmission energy as a function of several MPEG4 parameters. Results presented in this paper show that the proposed models are fairly accurate.
