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,...

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...

Ideal Hierarchical Secret Sharing Schemes
Hierarchical secret sharing is among the most natural generalizations of threshold secret sharing, and it has attracted a lot of attention from the invention of secret sharing until nowadays. Several constructions of ideal hierarchical secret sharing schemes have been pro-posed, but it was not known what access structures admit such...

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...

Alignment Based Precision Checking
Most organizations have process models describing how cases need to be handled. In fact, legislation and standardization (cf. the Sarbanes-Oxley Act, the Basel II Accord, and the ISO 9000 family of standards) are forcing organizations to document their processes. These processes are often not enforced by information systems. However, torrents...

Due to their out-standing performance (huge bandwidth and high signal quality), optical communications have become the standardized technologies suited for long reach and high bit-rate communication systems. Nevertheless, the traditional incompatibility of CMOS with the optical technology, and the difficulty for all-optical implementation of some key functions such as buffering...

Hardware/Software Mechanisms for Protecting an IDS Against Algorithmic Complexity Attacks
Intrusion Detection Systems (IDS) have emerged as one of the most promising ways to secure systems in the network. An IDS like the popular snort detects attacks on the network using a database of previous attacks. So in order to detect these attack strings in the packet, Snort uses the...

Exploiting Temporal Locality in Network Traffic Using Commodity Multi-Cores
Network traffic has traditionally exhibited temporal locality in the header field of packets. Such locality is intuitive and is very well studied over the years. In this paper, the authors study temporal locality in the packet payload. Temporal locality can also be viewed as redundancy and they observe significant redundancy...
