Receiver-Driven Routing for Community Mesh Networks
Community wireless mesh networks are decentralized and cooperative structures with participation rules that define their freedom, openness and neutrality. The operation of these networks requires routing algorithms that may impose additional unnecessary technical restrictions in the determination of routes that can restrict the freedom of community users. The authors propose...

Area and Laser Power Scalability Analysis in Photonic Networks-on-Chip
In the last decade, the field of microprocessor architecture has seen the rise of multicore processors, which consist of the interconnection of a set of independent processing units or cores in the same chip. As the number of cores per multiprocessor increases, the bandwidth and energy requirements for their interconnection...

Integrating ETL Processes from Information Requirements
Data Warehouse (DW) design is based on a set of requirements expressed as Service Level Agreements (SLAs) and Business Level Objects (BLOs). Populating a DW system from a set of information sources is realized with Extract-Transform-Load (ETL) processes based on SLAs and BLOs. The entire task is complex, time consuming,...

An energy harvesting transmitter operating in a point-to-point link through a discrete time fading channel is considered in this paper. Assuming non-causal knowledge of the harvested energy and channel state, the resource allocation that maximizes the mutual information is investigated by considering both the radiated power and the circuitry power...

On the Measurement of Privacy as An Attacker's Estimation Error
A wide variety of privacy metrics have been proposed in the literature to evaluate the level of protection offered by privacy enhancing-technologies. Most of these metrics are specific to concrete systems and adversarial models, and are difficult to generalize or translate to other contexts. Furthermore, a better understanding of the...

Scalable NoC Architectures: Efficient and Low Energy Consumption Chip Communication
Energy has been the primary reason for shifting from traditional single-core processors to current multicore processors. Such multicore designs require an interconnection network to communicate cores among themselves and with memory. As the number of cores per chip increases, the energy consumption of these Network-on-Chip (NoC) has become comparable to...
