Energy Efficient Coding and Transmission

چکیده
Efficient transmission of multimedia signals from energy limited portable devices requires a fresh look at the tradeoffs between source compression, channel coding and transmission strategies. In this paper we provide optimum operating points in terms of end-to-end source distortion and total energy consumption of the mobile due to compression, channel coding and transmission. We illustrate that the optimum strategy depends on the location of the mobile and that optimizing can prolong the battery life about ten times.

The imaging sensors are able to provide intuitive visual information for quick recognition and decision. However, imaging sensors usually generate vast amount of data. Therefore, processing and coding of image data collected in a sensor network for the purpose of energy efficient transmission poses a significant technical challenge. In particular, multiple sensors may be collecting similar visu...

One of the important issue in MANETs is energy saving. Recent studies show that Network coding can reduces energy consumption by less transmission in MANETs. Encryption/decryption, transmission cost and transmission time are worked as source of energy consumption in MANETs. Network coding provides intrinsic security based on which encryption can be done quite efficiently, but to provide securit...
متن کاملOptimal source coding and transmission power management using a min-max expected distortion approach
We consider the problem of compressing a video sequence for transmission over a wireless channel. In our approach we jointly consider error resilience and concealment techniques, at the source coding level, and transmission power management at the physical layer. We formulate a minimum -maximum distortion problem, where our goal is to either (i) minimize the total transmission energy for a give...

Energy-efficient transmission and bit allocation schemes are investigated in multisource single-sink Wireless Sensor Networks (WSNs). For transmission over Additive White Gaussian Noise (AWGN) channels with path loss, this work shows that the overall energy consumption can be minimised if each sensor transmits with the minimum power and cooperates with others in Time-Division Multiple Access (T...
