Abstract. The efficient use of the limited energy resources is the key challenge in the design of wireless sensor networks. Due to the paramount importance of the energy conservation, all protocols for these networks have to be designed taking into account their energy consumption. When simulation is used to analyze the performance of any energy-aware algorithm, it is necessary to have the info...

a numerical model for two-phase debris flows is developed in this paper, on the basis of understanding of the physical characteristics of debris flows from field investigations and experiments. employing a moving coordinate, the kinetic energy equation of gravel particles in unit volume in debris flow is developed by considering the potential energy of the particles, energy from the liquid phas...

In this paper, we propose a BlueGreen methodology to rethinking and redesigning network protocols, so as to satisfy the criteria of being service and energy efficiencies. The next generation networks (NGNs) are required to satisfy both extremely high levels of service resilience by the overprovision of redundant network resources (i.e., Blue criteria), and also minimising consumption of energy ...

Cloud Computing (CC) has been recognized and gained significant importance as an approach that can be used to save the energy of resources being used by organizations. CC is crucial in virtualization; that is helpful to reduce the use of the number of power consuming servers. Virtualization itself is being green as it is energy saving, cost effective and resource saving. For the use of resource...

Wireless sensor networks (WSN) are presented as proper solution for wildfire monitoring. However, this application requires a design of WSN taking into account the network lifetime and the shadowing effect generated by the trees in the forest environment. Cooperative communication is a promising solution for WSN which uses, at each hop, the resources of multiple nodes to transmit its data. Thus...

In Wireless sensor networks, the sensors are connected with the devices to observe their performance anddata. The Wireless sensor network, the energy consumed by the resources are measured across the remotelocation (base stations).There are varied performance metric used like network life to evaluate battery poweredsensor nodes.These nodes transfer the information packets from one station to a ...

Mobile Ad Hoc Networks (MANET) can be considered as a class of unstructured networks created by a number of autonomous wireless and sensor nodes. The inherent characteristics of such networks have made specific applications, such as multimedia transfer and challenging. Basically, the functionality of a node and very few resources directly affect the delivery of packets which depends on the ...

e nergy consumption has increased significantly in iran during the recent decades. in this study, an inter-industrial model has been improved to investigate the sources of the changes in the energy consumption of the country. the input-output tables of iran for the years 1988 and 2001 have been employed as the database of the model. the innovation of this research allows the researchers to stud...

black tea sample was dried by a vibro-fluidized bed dryer to find its aerodynamic behavior and thermal performance during drying. the drying experiments were conducted at three different inlet air temperatures of 100, 115 and 130°c and fluidization condition at five vibration intensity levels of 0 (no vibration), 0.063, 0.189, 0.395 and 1.184. the results showed that bed channeling and defluidi...
