Energy harvesting offers an attractive and promising mechanism to power low-energy devices. However, it alone is insufficient enable energy-neutral operation, which can eliminate tedious battery charging replacement requirements. Achieving operation challenging since the uncertainties in harvested energy undermine quality of service To address this challenge, we present a runtime energy-allocat...

It is expected that Wireless Body Area Network (WBAN) will greatly improve the quality of our life because of its myriad applications for our human beings. However, one of the challenges is to design energy efficient communication protocols to support the reliable communication as well as to prolong the network lifetime. Cooperative communications have the advantage of spatial diversity to comb...

The problem of binary hypothesis testing in a wireless sensor network is studied in the presence of noisy channels and for non-identical sensors. We have designed a mathematically tractable fusion rule for which optimal energy allocation for individual sensors can be achieved. In this thesis we considered two methods for transmitting the sensor observations; binary modulation and M-ary modulati...

The widespread application of wireless services and dense devices access have triggered huge energy consumption. Because of the environmental and financial considerations, energy-efficient design in wireless networks becomes an inevitable trend. To the best of the authors’ knowledge, energy-efficient orthogonal frequency division multiple access heterogeneous small cell optimization comprehensi...

In this paper, they study energy efficient resource allocation scheme for Orthogonal Frequency Division Multiple Access (OFDMA) systems with heterogeneous users. The trade-off between spectral and energy efficiencies is analyzed under the constraint of maintaining the fairness among users. They formulate the energy-efficient optimization problem as an integer fractional programming and present ...

This implementation aims towards the establishment of performance qualitative analysis on make span in VM task allocation and process according to their deadline, then implemented in CloudSim with Java language. Here major stress is given on the study of dead line based task scheduling algorithm with heterogeneous resources of the cloud, followed by comparative survey of other algorithms in clo...

The advances of the information and communication technology (ICT) brought changes in the energy distribution domain, introducing the Smart Grid (SG). In SG, generators, distributors, and consumers communicate in a bidirectional way. SGs are envisaged to include micro-grids (MG) consisting of distributed control networks of consumers, producers, and the power grid. Two-way communication in MGs ...

Battery powered transmitters face energy constraint, replenishing their energy by a renewable energy source (like solar or wind power) can lead to longer lifetime. We consider here the problem of finding the optimal power allocation under random channel conditions for a wireless transmitter, such that rate of information transfer is maximized. Here a rechargeable battery, which is periodically ...

An approach of doing register allocation beyond basic blocks for low energy is presented in this paper. With careful analysis of boundary conditions between consecutive blocks, our approach achieves the allocation results benefiting the whole program. By allowing the allocation results to propagate down block by block without backtracking, we avoid excessive computational cost.
