Due to the increasing consumer adoption of mobile devices, like smart phones and tablet PCs, saving energy is becoming more and more important. Users desire more functionality and longer battery cycles. While modern mobile computing devices offer hardware optimized for low energy consumption, applications often do not make proper use of energy-saving capabilities. This paper proposes detecting ...

Minimizing energy consumption is crucial for portable wireless communication systems because they operate on a limited battery supply. For example, the IEEE 802.11 standard includes a mechanism called power-saving mode (PSM), which allows a network interface on a mobile station to enter a sleep state whenever possible to reduce its energy consumption. However, the scheme needs to be complemente...

In this paper we propose a power-saving strategy for accessing the Internet from a mobile computer. Firstly, we measure the power consumption of a mobile computer that uses a TCP connection to send/receive data from the Internet. These measurements indicate that, by adopting TCP, the power consumption is negatively affected by the congestion in the fixed network. To solve this problem we extend...

Due to non inheritable restriction of sensors, there is always a vital issue on the way to utilize restricted energy effectively. In the proposed work we have focused on the Energy Consumption in WSN Using Mobile Sink and Hierarchal Clustering. There is concept of bringing mobile sinks to sensing field to save energy of cluster heads while sending data to mobile sinks instead of fixed sink on b...

Economists working with numerical solutions to the optimal consumption/saving problem under uncertainty have long known that there are quantitatively important interactions between liquidity constraints and precautionary saving behavior. This paper provides the analytical basis for those interactions. First, we explain why the introduction of a liquidity constraint increases the precautionary s...

Sustainable architecture is known as an important strategy in recent years and all around the world are cooperating to achieve this by use of natural elements. There are many examples of residential buildings in Iran s past and its traditional architecture that the architecture in the interim of paying attention to aesthetic issues and preserving the natural environment acts in a way that meets...

Energy crisis, global warming and other environmental issues are what motivate researchers to find new strategies to reduce energy consumption in buildings. Recently, using phase change materials (PCM) in the building’s envelopes has drawn significant attention as an energy-saving method, which helps in increasing the building’s thermal capacity. In the present research, the effects of the main...
