in iran the mainstreaming tool for integrating environmental concerns into energy sector is an energy-environment review (eer-iran). this paper comprises: (i) an analysis of the current situation with regards to energy production and consumption; (ii) an evaluation of the growth prospects with regard to energy production and consumption; (iii) the identification of environmental issues induced ...

Conventional Compressive Sampling (CS)-based data aggregation methods require a large number of sensor nodes for each CS measurement leading to an inefficient energy consumption in Wireless Sensor Networks (WSNs). To solve this problem, we propose a new scheme in the network layer, called “Weighted Compressive Data Aggregation (WCDA)”, which benefits from the advantage of the sparse randommeasu...

Wireless sensor networks (WSNs) are being envisioned for certain applications like habitat monitoring and environmental sensing. Wireless sensors are deployed to achieve network load balancing, prolonging network lifetime, and improving network coverage. To achieve these goals, energy estimation is one of the main constraints and concerns to consider, while deploying wireless sensors in a WSN f...

In this thesis we study the handoff problem of mobile stations (MSs) jointly with the resource management at the access points (APs) for wireless mesh networks (WMNs), where the APs can dynamically adjust the transmission power and time to each of the associated MSs. Two objectives are considered, one is to balance the energy consumption of the APs, and the other is to achieve fair throughput a...

Cloud computing has become an attractive technology to business persons due to its features such as virtualization and “pay-as-you-go” model. Now-a-days, balancing performance and energy consumption is a major issue in large data centers. Energy has become a leading design constraint for developers and they try to explore new techniques to reduce energy consumption. This work is to address the ...

Combinatorial decision problems arise in many different domains such as scheduling, routing, packing, bioinformatics, and many more. Unfortunately, most of these problems are NP-complete. Despite recent advances in developing scalable solvers, there are still many problems which are often very hard to solve. Typically the most advanced solvers include elements which are stochastic in nature. If...

Cloud computing is an expanding area in research and industry today, which involves virtualization, distributed computing, internet, and software and web services. This paper presents an approach for scheduling algorithms that can maintain the load balancing. In this research work we have developed power optimization algorithm which over comes the limitations of the previous algorithms[Round Ro...

in wireless sensor networks, optimal consumptionof energy and having maximum life time are important factors. in this article attempt has been made to send the data packets with particular reliability from the beginning based on aodv protocol. in this way two new fields add to the routing packets and during routing and discovering of new routes, the lowest remained energy of nodes and route tra...
