There has been an effort for a few decades to keep energy consumption at minimum or least within low-level range. This is more meaningful and complex by including customer’s satisfaction variable ensure that customers can achieve the best quality of life could be derived from how used different devices. We use concept Shapley Value cooperative game theory solve multi-objective optimization prob...

In this paper, a transmitting power allocation strategy for users jointed together pre-coding is presented to eliminate interusers interference and improve the energy efficiency of Massive MIMO systems. The power allocation model is formularized as energy efficiency optimization problem of the users ’ power and circuit power consumption. We demonstrate that energy efficiency is a convex functio...

When environmental conditions vary stochastically, individuals accrue fitness benefits by exhibiting phenotypic plasticity. Here we analyze a general dynamic-programming model describing an individual's optimal energy allocation in a stochastic environment. After maturation, individuals repeatedly decide how to allocate incoming energy between reproduction and maintenance. We analyze the optima...

The issue of management and allocation of resources in cloud computing environments, according to the breadth of scale and modern technology implementation, is a complicated issue. Issues such as: the heterogeneity of resources, resource dependencies to each other, the dynamics of the environment, virtualization, workload diversity as well as a wide range of management objectives of cloud servi...

The ability to store energy enables organisms to deal with temporarily harsh and uncertain conditions. Empirical studies have demonstrated that organisms adapted to fluctuating energy availability plastically adjust their storage strategies. So far, however, theoretical studies have investigated general storage strategies only in constant or deterministically varying environments. In this study...

Java has become a popular choice for implementing various applications that run on mobile and hand-held devices. Optimizing the energy consumption in mobile environments is of critical importance to prolong the battery life. In this work, we propose an object allocation strategy to reduce the energy consumption of Java applications. This object allocation strategy uses a part of the on-chip mem...

Memory systems consume significant energy in hand-held embedded systems. Existing techniques for reducing memory energy requirements in low-power systems have addressed energy consumption when the system is turned on; but we also consider data retention energy during the power-off period. Semiconductor non-volatile memory is indispensable for hand-held devices that cannot afford magnetic disks ...

The lifetime of the emerging Wireless visual sensor network (WVSN) is seriously dependent on the energy shored in the battery of its sensor nodes as well as the compression and resource allocation scheme. In this paper, the energy harvesting technology was adopted to provide almost perpetual operation of the WVSN and compressed-sensing-based encoding was used to decrease the power consumption o...
