提出了一种用于无线视频传感器网络的H.264/AVC帧内编码器的能耗预测模型。这样的模型是非常感兴趣的能量受限的上下文中，如WVSN，其中视频流在传输之前进行处理。事实上，考虑到处理和传输的消耗能量允许全局能量消耗的优化。所提出的模型预测处理的能量消耗的基础上考虑的量化参数（QP）和帧速率（FR）的值。该模型的通用形式使其能够预测任何基于H.264/AVC帧内的编码器的能耗。仿真结果表明，该模型的准确性，这是验证不同的分辨率下，QP和FR，平均预测误差为4%。
This paper proposes a model to predict the energy consumption of a H.264/AVC intra-only based encoder designed for the wireless video sensor networks (WVSNs). Such model is of great interest in an energy-constrained context like the WVSN, where the video streams are processed prior to transmission. In fact, accounting for both processing's and transmission's consumed energies allows the optimization of the global energy consumption. The proposed model predicts the processing's energy consumption based on the considered Quantization Parameter (QP) and the Frame Rate (FR) values. The generic form of this model enables it to predict the energy consumption of any H.264/AVC intra-only based encoder. Simulation results demonstrate the accuracy of the proposed model, that is validated under different resolutions, QP and FR, with an average prediction error of 4%.
