This work is focused on the characterization of the traffic allocated in Elastic Optical backbone networks when different dynamic traffic profiles are generated. Extensive simulations are done to statistically model the real-time traffic carried by this kind of networks. Well known topologies such as NSFNet and US_Backbone are considered as well as different parameters applied to the traffic generation...
Power management is a primary challenge in the wireless sensor network (WSN). In order to reduce power consumption by network, data aggregation is introduced. Data aggregation is based on Tree topology often called as Data Aggregation Tree (DAT). DAT is mostly adopted in periodically monitoring applications of WSN. All existing work did not consider the transitional region and Load factor on each...
In islanded microgrid system, the battery tends to be the most vulnerable element in terms of durability. Poorly managed battery charge/discharge process is one of the main life-limiting factors. To improve the battery life, a novel energy storage system topology and a power allocation strategy are proposed in this paper. A standalone 6kW Photovoltaic (PV) microgrid system with hybrid energy storage...
A model is under development for the simulation of Central-European electricity market forecast for the next 5-10-15 years. Taking into account the different development scenarios and the bottle necks, we investigate the compensation flows in the coupled markets and the price trends. A large data set was collected from international forecasts. Based on these data generation capacities and prices,...
The problem of burst losses in OBS networks has an impact on the service quality perceived by end users. In order to guarantee certain level of Service Quality (QoS) in terms of burst losses, wavelength resources have to be dimensioned properly. In this paper, we address the problem of the Virtual Topology (VT) design that concerns the establishment of explicit routing paths and the allocation of...
Chip multiprocessors (CMPs) combine increasingly many general-purpose processor cores on a single chip. These cores run several tasks with unpredictable communication needs, resulting in uncertain and often-changing traffic patterns. This unpredictability leads network-on-chip (NoC) designers to plan for the worst case traffic patterns, and significantly overprovision link capacities. In this paper,...
A term virtual capacity layer concerns multilayered model of the network. That kind of models refer to networks compounded of different layers of resources where different topologies in each layer are possible. Virtual capacity (VC) layer describes a network topology which is situated directly above transport layer. This paper focuses on topology of VC layer and its influence on the dimensioning issue...
Building on the extensive research in Virtual Reality (VR), we are proposing a new dynamic prototype for modelling and simulating carbon emissions in a virtual village called VIRVIL. VIRVIL is a simulated settlement for the assessment of the impact of low and zero carbon technologies and measures in the built environment. The prototype will focus on the impact on the community as a whole, as well...
In this paper we present an algorithm, based on power management of access points (AP), to reduce congestion in wireless local area networks (WLANs). The algorithm finds the most congested access point (MCAP) and adjusts its transmitted power in discrete steps and determines the optimal userspsila assignment such that an optimal load distribution is achieved. Results show that the algorithm is capable...
