Analysis of Researcher Co-authorship Network

This work analyzes the co-authorship of science papers published by university teachers, and then constructs are searcher co-authorship network and characterizes the network by some varying quantities: the clustering coefficient, the average degree, diameter, average distance and components. Consequently, this paper visualizes the researcher co-authorship network which can lead to a better understanding of the applications of information visualization […]

Survivable virtual infrastructure mapping with dedicated protection in transport software-defined networks [Invited]

Efficiently mapping multiple virtual infrastructures (VIs) onto the same physical substrate with survivability is one of the fundamental challenges related to network virtualization in transport software-defined networks (T-SDNs). In this paper, we study the survivable VI mapping problem in T-SDNs with the objective of minimizing the VI request blocking probability. In particular, we address the subproblems […]

RAON: A recursive abstraction of SDN control-plane for large-scale production networks

In this invited paper, we introduce RAON: a recursive abstraction of SDN control-plane for large-scale production networks. RAON leverages a recursion, where the solution to a problem depends on solutions to smaller instances of the same problem, and organizes them in hierarchical domains. To this end, RAON abstracts the details of the underlying network as a […]

Social networking for Smart Grid users

Emerging smart grids have promising potentials to make energy management more efficient than currently possible in today’s power grids. Integration of small scale renewables, distributed charging of electrical vehicles and virtual power stations are some of the technological innovations made possible by smart grids. Besides these technological aspects, smart grids also have a clear social component: consumers and small producers can […]

Has Time Come to Switch From Duty-Cycled MAC Protocols to Wake-Up Radio for Wireless Sensor Networks?

Duty-cycled Medium Access Control (MAC) protocols certainly improve the energy efficiency of wireless networks. However, most of these protocols still suffer from severe degrees of overhearing and idle listening. These two issues prevent optimum energy usage, a crucial aspect in energy-constrained wireless networks such as wireless sensor networks (WSNs). Wake-up radio (WuR) systems drastically reduce these problems by completely […]
