The Software-Defined Networking (SDN) paradigm allows networking hardware to be made “malleable” and remotely manageable by the so-called SDN controllers. However, the current SDN landscape is extremely fragmented. Different open and closed source controller frameworks such as Open-Daylight , Ryu , Floodlight , etc. exist. Porting SDN applications from one such platform to another is […]
The growing emergence of a variety of network applications have stringent Quality of Service (QoS) requirements which cannot be always met by the best-effort Internet. To provide QoS, several QoS frameworks have been explored over last two decades, but none of them has been truly successful and globally implemented. This paper proposes QOF, a novel […]
The emerging smart utility networks (SUN) provide two-way communications between smart meters and smart appliances to achieve low power usage, low cost and high reliability. Because SUN are composed of dense wireless devices, signal interference between the devices is an inevitable problem. This paper presents a precoder design that can reduce the effects of interference […]
In this paper, we have proposed a Cognitive Radio system where primary users uses the precautionary measures against the possible interferences that may disturb their quality of service (QOS), these interferences may be originated from any other primary user itself, possibly due to the effect of the hidden terminal problem or may be received from […]
PMUs play an essential rule in monitoring and control of power network. However, it is not possible to install PMUs at all buses of network, due to economical and technical constrains. Therefore, optimal PMU placement (OPP) is done to obtain full observability of network with minimum number of PMUs and maximum redundancy. On the other […]
For the better integration of distributed and renewable generation, new investments in innovative distribution networks, such as active distribution networks and smart grids (SGs), are required. Regulators should decide what incentives are desirable to create a flexible economic regulatory framework that can drive distribution system operators to invest in innovation and in active distribution networks. […]
This paper presents a risk-based advanced distribution network management system (NMS) aimed at maximizing wind energy harvesting while simultaneously managing congestion and voltages. The NMS allows the adoption of multi-minute control cycles so the volume of actions from on-load tap changers (OLTCs) and distributed generation (DG) plants can be reduced while effectively catering for the […]
NASAs Space Network has been a successful program that has provided reliable communication and navigation services for three decades. As the third generation of satellites is being launched, alternatives to the current architecture of the system are being studied in order to improve the performance of the system, reduce its costs and facilitate its integration […]
We propose a joint multi-layer planning algorithm for IP over flexible optical networks, and use it, to compare the performance of joint as opposed to sequential multi-layer network planning in terms of spectrum and cost.
In Cyber-Physical Networked Systems (CPNS), the adversary can inject false measurements into the controller through compromised sensor nodes, which not only threaten the security of the system, but also consume network resources. To deal with this issue, a number of en-route filtering schemes have been designed for wireless sensor networks. However, these schemes either lack […]
