This paper evaluates switch-over time of a failure protection in a software-defined network (SDN). In the area of network protection, it is very necessary to overcome the link failure. This failure may cause the traffic interrupted and the packets are lost in the network. In this case the time of recovery of the failure should be as short as possible. In case of open shortest path first (OSPF) network,...
For stabilizing power frequency in the grid, demand-supply balancing capability by manipulating the demand side, known as Demand Response (DR), is getting attention because of the continuous increase in renewable energy resources and deferrable loads such as electric vehicles in addition to the traditional adjustment function by supply side such as thermal plants. In the future smart grid, it is imperative...
This paper shows the effectiveness of the system that controls the network route based on social information. An automatic route control is performed with the network virtualization node FLARE that uses VLAN coupling between each base of the wide area network test bed called JGN-X as a platform.
This paper proposes a source-based high-speed wavelength-path protection scheme configuring a tree-shaped backup path in WDM networks. In the proposed scheme, a failure-detecting node on a primary path starts protection by sending a failure notification to a source node of the primary path through the tree-shaped backup path. Intermediate nodes on the backup path and the source node which receive...
Traffic variation heavily impacts energy savings achieved by putting Line Cards (LCs) into Sleep Mode (SM) in core Internet Protocol (IP)-over-Wavelength Division Multiplexing (WDM) networks. We propose a simple traffic model covering temporal and spatial traffic variation and investigate the impact of (controlled) traffic variations on energy savings achieved with the Energy Watermark Algorithm (EWA)...
Communication networks are changing. They are becoming more and more "software-based." The use of Network Function Virtualization (NFV) to run network services in software enables Software Defined Networks (SDN) to create a largely software-based network. To truly achieve the vision of a high-performance software-based network that is flexible, lower- cost, and agile, a fast and carefully...
In the paper it has been proposed to use a fuzzy-controller in telecommunication networks for improving the routing process. An architecture of the fuzzy-controller was developed. Linguistic variables, terms and membership functions for input and output values have been defined. Rules base has been developed. The operation of the fuzzy-controller has been simulated.
This paper presents a mixed integer linear programming (MILP) model for the daily planning of home health care (HHC) services provided by the crew of HHC firms. The model takes into account the time window of patients, compatibility requirements, workload limits of staff and distance of patients. The quantitative values of these parameters along with the similarity or difference within the values...
Dynamic Energy investment funds streamlining gets to be one of the significant worries in the remote sensor system (WSN) directing convention outline, because of the way that most sensor hubs are furnished with the constrained non rechargeable battery power. In this paper, we concentrate on minimizing vitality utilization and amplifying system lifetime for information transfer in one-dimensional (1-D)...
The recent development in Wireless Sensor Networks (WSN) has proven that the WSN can be deployed in the Global Wireless Telecommunication with marginally high performance in terms of low power consumption, scalability, adaptability, reliability, security and data delivery. The implementation of WSN in wireless tele-communication using the proposed N-Tier Spherical Grid Routing (NSGR) WSN's architecture...
The Wireless sensor networks (WSN) is functional in various environments namely surveillance of forest, earth quake monitoring, medical applications etc. This paper tackles with the problem of WSNs with detection of the target with dynamic considerations and random deployment of node. The proposed work explains initial environments of Energy Efficient Distributed Receiver Based Routing Protocol (EEDR)...
The MANET [mobile ad-hoc network] is most popular and most applicable term and MANET consists of number of mobile nodes, and each independent node in the MANET can communicate with the other node without any wire connections. In the presence of malicious nodes in the MANET, Leads to serious security problem because it will disturb the entire routing processes. So in this paper we are introducing a...
A mobile adhoc network is an independent system of mobile stations associated by wireless link to form a system. This system can be modeled in the form of an uninformed graph. Adhoc networks are peer to peer, multihope networks were data packets are transmitted to a source to destination through intermediate nodes (which serve as router). The infrastructure is not the main issue to setup MANET and...
An automated fuel-optimal air traffic management system for airport ATC (Air Traffic Control) is proposed in this paper. The paper proposes a novel methodology for routing and management of aircraft within the airspace managed by the ATC (Air Traffic Control) of an airport. The proposed system will allocate the most fuel efficient combination of runways at the airport to specifically cater to the...
WSN(Wireless sensor network) depicted as an emerging technology, with its potential applications in the field of territory monitoring and industrial applications. The sensors employed in the surrounding environment will monitor the physical attribute changes such as temperature, humidity, etc. and makes notice of the data being gathered and delivers the gathered information to the (BS) base station...
The primary goal of the wireless sensor network is to provide the maximum coverage of the sensing area required mainly in applications like battlefield and surveillance etc. With the limited battery of the nodes covering the maximum area over a longer duration is an critical issue. Hence in this paper an efficient algorithm which maintains maximum coverage along with balance of load on the nodes is...
A fundamental problem in QoS (quality-of-service) routing is the multi-constrained path (MCP) problem. The MCP problem used the shortest path with respect to a single edge weighting function as an approximate solution to MCP. For solving MCP problem was offered a lot of methods. One of these methods is based on Lagrangian Relaxation. These algorithms allow finding the shortest paths from the source...
Since traffic diversity and volume increase with growing popularity of mobile applications, there is the strong need to manage the traffic carried by networks. Software defined networking can manage network while enabling new services by employing traffic management whose goal is to maximize the utility objective while satisfying given requirements. In this paper, we propose an efficient routing to...
