Scalable and reliable routing is a critical issue in sensor network deployment. A number of approaches have been proposed for sensor network routing, but sensor field implementation tends to be lacking in the literature. In our study, the problems of scalability and reliability in sensor network routing are addressed through a simple but powerful scheme(More)
— Previously, traffic simulation on FPGAs was limited to very short road segments or required a large number of FPGAs. The appearance of large (3 – 10M gate) FPGAs with a large number of input/output pins (up to 1200) allows for large amounts of data to be processed concurrently. This work shows that traffic simulation of entire metropolitan areas is(More)
This work demonstrates that road traffic simulation of entire metropolitan areas is possible with reconfigurable supercomputing that combines 64-bit microprocessors and FPGAs in a high bandwidth, low latency interconnect. Previously, traffic simulation on FPGAs was limited to very-short road segments or required a very large number of FPGAs. Our data(More)
Often reconfigurable systems are reported to have 10× to 100× speedup over that of a software system. However, the reconfigurable hardware must usually be combined with software to form an entire system. This system integration presents a hardware/software co-design problem with many system engineering issues. Here, we present traffic acceleration on the(More)
— By using self-assembling fabrication techniques at the cellular, molecular, or atomic scale, it is nowadays possible to create functional assemblies in a mainly bottom-up way that involve massive numbers of interconnected components. However, such assemblies are often highly irregular, unreliable, and heterogeneous. A grand challenge for future and(More)
