This paper considers the optimal energy-efficient transmission policy in time-sharing multiuser systems with a hybrid energy harvesting transmitter. The system operation energy is supplied by a constant energy source which is driven by a non-renewable resource and an energy harvester which harvests energy from its surrounding environment. Our goal is to maximize the energy-efficient transmission of...
In this paper, a power-signature-based Bayesian multi-classifier is proposed to identify various operational modes of a complex machinery system that can help determine the energy contribution of different operation modes, identify potential energy hot-spots and provide basis for more accurate energy consumption calculation. This technology can also help process experts and managers to perform the...
The problem of high energy consumption of data centres has become increasingly serious. Computing and cooling energy are the most significant parts. On one hand, as the energy consumption of under-utilized resources accounts for a substantial amount of the actual energy draw, load consolidation is widely used for reducing computing energy by increasing resource utilization. On the other hand, to avoid...
Mobile Cloud Computing (MCC) enables mobile devices to use resource providers other than mobile devices themselves to host the execution of mobile applications. Recent research shows that it is more suitable for mobile devices to offload complex real-time applications to the cloud formed by nearby mobile devices, referred to as the local mobile cloud, because of low communication latency. In this...
A novel application-specified MAC cross-layer design approach is proposed for wireless sensor networks. By using SWE architecture and Sensor ML, the sensor ontology is constructed, and the special inference ruler for MAC is defined by adopting computation geometry algorithms. By integrating application semantics with 802.11 and SMAC protocol, we propose the novel MAC protocols. The redundancy among...
For the energy consumption problem of wireless sensor networks, a mobile agent routing based on improved genetic algorithm (MARIGA) is proposed in this paper. This algorithm introduces a new crossover strategy and mutation operator to effectively control the premature stagnation in the convergence process. The simulation results indicate that the MARIGA algorithm can effectively improve the routing...
Xiang Lia Load-balancing Clustering Algorithm of WSN for Data Gathering (LCA-DG) is proposed based on load equalization. The LCA-DG uses the comprehensive weight value that composed of two factors, that distance between head and members and residual energy, to improve cluster members choice strategy for balancing load of each bunch, and uses optimization threshold value and receiving threshold value...
Experimental study of warm plasma reforming carbon dioxide and methane to syngas is presented. To achieve better plasma reforming methods for industrial chemical application, the characteristics of the different plasmas are reviewed. The warm plasma combines advantages of both thermal and non-equilibrium discharge, which is the more potential for industrial application than others plasmas, such as...
