Wireless sensor networks(WSN) have unique properties that distinguished them from other wireless networks and have special challenges. Not-chargeable, not-changeable and limited power supplies of sensor nodes is the most important challenge of this networks, and if the power supply of node expired, a part of data maybe lost. Because of the importance of covers in wireless sensors, in this work ...

Electricity Distributions Networks (DNs) are changing from a once passive to an active electric power system element. This change, driven by several European Commission Directives and Regulations in the energy sector prompts proliferated integration of new network elements, which can actively participate operations if adequately utilized. paper addresses possibility using these DN elements for ...

This paper reviews the characteristics and methodologies developed by the programmable network and active network communities as complementary approaches making a significant contribution to the development of new architectures. It reviews the characteristics and methods developed for policy-based network management, specifically in the context of active networks. A network management overview ...

To ease the transition towards the future of distribution grid management, regulators must revise the current interaction model, that is, the set of rules guiding the interactions between all the parties of the system. Five interaction models are proposed, three of them considering active network management. This paper evaluates the economic efficiency of each model using macroscopic representa...

Active networks enable to deploy new services at run–time by using mobile code. While considerable effort is under way to build active network infrastructures and to understand how to create corresponding services, less is known about how to end them. A particular problem is the coordinated steering of mobile code based services, especially in the case of “strong” active networks where each dat...

Random Early Detection (RED) is one of the most commonly used Active Queue Management (AQM) algorithms that is recommended by IETF for deployment in the network. Although RED provides low average queuing delay and high throughput at the same time, but effectiveness of RED is highly sensitive to the RED parameters setting. As network condition varies largely, setting RED's parameters with fixed ...
