Network on Chip (NoC) is a new paradigm that can solve the problems related to System on Chip (SoC) design. These problems and challenges become more significant when the complexity of SoC increases. The vast volume of these challenges requires a new and flexible NoC test framework (simulator) to be investigated. We have developed a general purpose SystemC based NoC simulator that employs some new...
One of the key enhancement elements of next generation LTE networks is the deployment of relays. Relays provide added performance gains in the form of enhanced coverage for mobile UEs situated in poor coverage areas. Relays provide coverage gains in high shadowing areas and also help reduce power consumption at the UE terminal by enabling a better communication channel. A striking aspect of relays...
It is developed a case study, unifying theoretical and practical aspects, concerning planning and implementation of orthogonal frequency division multiplexing (OFDM) point-to-multipoint (PtMp) links at Industrial, Scientific and Medical (ISM) 5 GHz band. The proposed design methodology is validated using analytical results and field measurements.
High performance implementation of 2D digital filters are highly desired in many applications for real-time processing. In this paper, a multiprocessor realization of a 2D denominator separable digital filter is implemented in Altera Stratix III FPGA. The implementation achieves a data throughput equivalent to one multiplication and two additions, plus one clock cycle. It has been found that the maximum...
The Internet is an interconnection of Autonomous Systems (ASes) of which many are controlled by Internet Service Providers (ISPs). ASes use Border Gateway Protocol (BGP) to communicate routing information to each other. BGP does not allow a network to control how its traffic is routed. As a result, traffic belonging to a specific network can be intentionally dropped as it is routed by BGP through...
In this paper we investigate the combination of Adaptive Modulation and Coding (AMC) and Hybrid Automatic Repeat reQuest (HARQ) techniques in an orthogonal cooperative scheme using infra-structured (fixed) relays. We consider realistic large scale and small scale path loss models, taking into account the antennas heights and the presence or not of line of sight (LOS). Results demonstrate that large...
Cognitive radio technology has received increasing attention recently as a solution for the spectrum scarcity problem in wireless technology. It allows radios to intelligently locate free frequencies and use them efficiently. In our work, the unused spectrum is used to serve secondary users who do not have a license to access the spectrum. We propose a cluster-based architecture to form a secondary...
Co-operative relay is emerging technique for 3G/4G high bandwidth networks in order to improve the capacity of edge nodes. As the deployment cost is high, there might be a few number of relay nodes in the cell which can help the edge nodes to transmit their data. From this perspective, one of the key problems for a relay node is to make decision which edge nodes to help and how much resource need...
The recent emergence of the sensor networks technology is significantly impacting the capabilities for automated distributed monitoring of environments. The low manufacturing cost of sensors, increased coverage and accuracy in distributed sensing due to their large deployments and their ability to operate in inhospitable terrains has made them an amenable technology for various surveillance and monitoring...
