A flexible Wireless Sensor Network platform for implementation of diverse applications has been developed and deployed at Instituto Superior Técnico - Technical University of Lisbon (IST-TUL). Since its initial deployment in 2007, this testbed has grown st ...
Complex networks exist for a number of purposes. The neural, metabolic and food networks ensure our survival, while the social, economic, transportation and communication networks allow us to prosper. Independently of the purposes and particularities of th ...
We consider multisource non-coherent network coding, where multiple sources send information to one or multiple receivers. We prove that this is equivalent to a ldquosubspacerdquo channel, that takes subspaces as inputs and outputs. We then show that the r ...
Providing real-time multimedia services over a best-effort network is challenging due to the stringent delay requirements in the presence of complex network dynamics. Multiple description (MD) coding is one approach to transmit the media over diverse (mult ...
The aim of the present invention is a method to achieve the customization of the communication network of a multicore communication system. This goal is achieved thanks to a method to design a multicore communication system, said communication system compr ...
Nowadays, advances in telecommunication network design and performance analysis often rely on dedicated software tools. Unfortunately, developing new tools is a very time and resources consuming activity. To rationalise development costs, existing applicat ...
The framework of complex networks has been shown to describe adequately a wide class of complex systems made up of a large number of interacting units. In this framework, a node is associated to each unit and two nodes are connected by an edge if the two u ...
A flexible Wireless Sensor Network platform for easier implementation of diverse applications has been developed and deployed at one of the Instituto Superior Técnico - Technical University of Lisbon (IST-TUL) campus. Since its initial deployment in 2007, ...
We examine routing over two classes of orthogonal information networks. The first is a relay network with orthogonal inputs. The nodes in this network do not broadcast, but communicate to the different nodes via independent inputs. There is multiple access ...

A method is proposed to robabilistically map location observations to the underlying network. Instead of generating a single path as the map matching algorithms do, this method aims at calculating a likelihood for each potentially true path to have been th ...
