Energy Consumption Rate

<p>To increase the network lifetime of WSNs is a major concern. Network lifetime can be increased by reducing energy consumptions through MAC protocols periodic and a- periodic sleep mode mechanisms. The short duty cycle makes sensors have low energy consumption rate but increases the transmission delay and long duty cycle makes the sensor to increase the energy consumption and reduce the delay. Duty cycle need to be adaptively varied to reduce the idle listening. In the proposed Adaptive Duty cycle MAC (ADMAC) protocol, duty cycle is varied by taking nodes rate of energy consumption and filled queue length in account. It reduces the delay and energy spent by reducing the idle listening. ADMAC is realized in NS2 and its performance is compared with SMAC.</p>

High Energy Storage Density

Transportation accounts for more than a quarter of total global energy consumption. For fuelling road transportation there has been much speculation about the use of hydrogen as an energy carrier, which proponents claim would usher in the “Hydrogen Economy”. The concept of the “complete energy conversion chain” has been used to compare the overall energy consumption and CO2 emissions from vehicles powered by hydrogen fuel cells with those from vehicles using a battery and electric drive. The analysis shows that if a sustainable source of electricity is used to produce hydrogen, then the hydrogen and fuel cell system is just equivalent to a battery. The efficiency of these two different approaches has been compared, and shows that the hydrogen system would consume nearly three times the primary energy required by a battery storage system. Conventional batteries do not, however, have a sufficiently high energy storage density to provide the range needed for most drivers. A new generation of plug-in hybrid vehicles is being developed which take advantage of the best attributes of both electric vehicles and conventional fossilfuelled vehicles. These vehicles show promise to dramatically reduce the quantity of greenhouse gases produced each year by the transportation sector.

Energy Consumption Rate

In this article a mathematical model for thermal protection level analysis is developed. It is based on the consumption rate of primary energy. It allows to calculate the relevant thickness of the selected insulation material under any climatic and economic conditions with any constant layers of building envelope taken from structural considerations. The key factors influencing the model are also evaluated. The main factors to influence the energy model are the region degree-days and the energy consumption rate for the production, transportation and installation of the insulation material. The following results were reached: this approach requires the data, which sometimes has no public access, provides us with an objective assessment criteria when comparing the level of building thermal protection in different countries.
