The paper proposes to realize a simulator for testing roaming algorithms in wireless networks. The simulator is made as a Windows application, which commands through USB the attenuators. The attenuators are related with the Access Points (APs). Proximity or the distance, of the mobile client (CL) com-pared to AP, is simulated by changing attenuation of the signal path derived from the AP's antenna...
As the scale of System-on-Chip (SoC) grows rapidly in recent years, the communication burden between on-chip elements becomes much greater than before. Network-on-Chip (NoC) has been proposed as a solution for this issue. However, it is difficult to use mathematical models to analyze the application-specific NoC with various topologies, switching architectures and routing algorithms. Existing simulators...
Networks on chips (NoCs) provide a mechanism for handling complex communications in the next generation of integrated circuits. At the same time, lower yield in nano-technology, makes self repair communication channels a necessity in design of digital systems. This paper proposes a reliable NoC architecture based on specific application mapped onto an NoC. This architecture is capable of recovering...
With technology scaling, vulnerability to soft errors in random logic is increasing. There is a need for on-line error detection and protection for logic gates even at sea level. The error checker is the key element for an on-line detection mechanism. We compare three different checkers for error detection from the point of view of area, power and false error detection rates. We find that the double...
