Energy consumption has already become a major challenge to the current Internet. Most researches aim at lowering energy consumption under certain fixed performance constraints. Since trade-offs exist between network performance and energy saving, Internet Service Providers (ISPs) may desire to achieve different Traffic Engineering (TE) goals corresponding to changeable requirements. The major c...

We consider differentiated bandwidth allocation for short-range wireless personal communication systems: Bluetooth. Since bandwidth requirements may vary among applications/services, and/or it may change over time, it is important to decide how to allocate limited resources to various service classes to meet their service requirements. We propose a simple and eff icient bandwidth allocation mec...

The largest energy consumption, particularly electricity use, for residential users and service industry is attributed to air-conditioning systems. Although novel design can yield energy-efficient air-conditioning systems, there is still room for reducing energy consumption by the control of their operation, especially for those already installed. This study presents a slow intelligence framewo...

Commonly used consumption/saving models have radically different implications for households response to income shocks, ranging from the hands-to-mouth model, where consumption bears all the adjustment, to the complete markets model, where wealth bears all the adjustment. In this paper we use the Italian Survey of Household Income and Wealth, which is the only available micro dataset that conta...

Mass consumption of energy is a big problem. Energy-saving activities which are a solution to this problem have been attracting a lot of attention. Nevertheless, in order to engage in thorough energy-saving activities, consumers need support; on the other hand, even with support, the effects seem to be only temporary. In this paper, to obtain a long-term effect, we focus on developing a method ...

existed electricity grids deliver produced power to the consumer passing through transmission and distribution grids. according to high losses of these grids in transmission level and inexistence of bilateral interaction for simultaneous information exchange, a concept of smart grids were made by capabilities such as consciously participation of consumers in the smart electricity grids, an amou...

This paper examines the impact of family size on household saving. We first study a theoretical life-cycle model that includes finite lifetimes and saving for retirement and in which parents care about the consumption of their dependent children. The model implies a negative relationship between the number of dependent children in the family and the household’s saving rate. Then, we test the mo...

We study consumption/saving decisions in an environment in which agents face a conflict between present and future utility which may require self-control for its resolution. We derive behavioral foundations for our analysis of self-control from the cognitive sciences, and in particular from the study of cognitive control in ‘delayed response’ tasks. In our model, self-control requires the activ...

Routing in Wireless Sensor Networks (WSNs) is a very challenging task due to the large number of nodes, their mobility and lack of proper infrastructure. Since the sensors are battery powered devices, energy efficiency is considered as one of the main factors in designing routing protocols in WSNs. Most of energy-aware routing protocols are mere energy savers that attempt to decrease the energy...
