Mobile robots collaborate in order to solve efficiently the central problems in algorithmics of distributed computing like searching/exploration, rendez-vous or pattern formation.

Many data collection protocols have been proposed to cater for the energy-efficient flow of sensor data from distributed sources to a sink node. However, the transmission of control commands from the sink to one or only a small set of nodes in the network is generally unsupported by these protocols.

Traditional distance vector routing and efficient flooding-based routing can be considered the two ends of the routing continuum in wireless sensor networks. The former uses a graph metaphor to find the best paths between the end-points in a network.

Networking research and development is an important field in information technology and its importance grows with the rise of the Internet and the ubiquity of worldwide communication.

Information overload has become an ubiquitous problem in modern society. Social media users and microbloggers receive an endless flow of information, often at a rate far higher than their cognitive abilities to process the information.

The Internet's Transport Layer has been defined by TCP and UDP for the last 30 years. The minimal functionality of UDP enables application developers to develop their own proprietary protocols - there are plenty of examples.

This paper presents a simple framework, called WalkAbout, to infer a coarse view of connectivity in very large graphs; that is, identify well-connected “regions" with different edge densities and determine the corresponding inter- and intra- region connectivity.

With the increasing availability of configurable network equipments, the research has moved from proposals to improve quality of service in the wireless standards, to complete potential chaos when it becomes accessible to every user. In this talk we go through this evolution and discuss its impact on the network and on the user.

Virtualization is a powerful paradigm in computer science, as it allows to decouple software and services from the constraints of the underlying physical infrastructure. Virtualization is also one of the main innovation motors in today's Internet

Visible light is ubiquitous in the cyber-space nowadays. In this talk, I will introduce our recent work about how to harness visible light for mobile computing applications in both temporal and spatial design domains. Our work leverages the fact that the fluorescent light intensity changes with a stable period, which can serve as both a global time reference and an indoor environment indicator.
