摘要

This paper mainly analyzes the main factors influencing the nodes' energy consumption in ultra wide-band (UWB) wireless multimedia sensor networks (WMSNs) and how they affect the sensors' energy consumption. First, the effect of the transform coder's dimension in an additive white Gaussian noise (AWGN) channel on sensor energy consumption is analyzed, and then, the effect of the maximum allowable distortion on energy consumption for a practical H.264 wireless video transmission. The simulation results show that, the source coder and decoder dissipate most of the sensor energy consumption. In the AWGN channel, the energy consumption is directly influenced by the transform code's dimension and there exists an optimal transform coder dimension to tradeoff the coding efficiency and the communication energy consumption. Further, when the H.264 standard is employed, the ratio of the communication energy consumption to the total energy consumption decreases with the maximum allowable distortion's increasing.
