This paper evaluates energy level performance of three packet delivery schemes in a Wireless Sensor Networks (WSN) in multipath Rician fading channel. Three different information delivery mechanisms are investigated using regenerative relays with or without error correction capability. Energy consumption for successful delivery of a data packet for each mechanism is evaluated and compared under several...
The actual traffic data collected on various applications specific on-chip networks exposed that the network traffic is self-similar in nature. In this work, modeling of self-similar traffic by aggregation of a large number of on-off Pareto sources has been discussed. We have developed a cycle accurate network simulator for evaluating the performance of wormhole router based network by varying locality...
Lithography related CD variations, fluctuations in dopant density, oxide thickness and parametric variations of devices are identified as major challenges in ITRS. Due to growth in size of embedded SRAMs as well as usage of sense amplifier based signaling techniques, process variation in sense amplifiers lead to significant loss of yield. In this paper, we present a process variation tolerant self-compensating...
Recent expansion in the demand for high performance applications require high performance devices. It can be achieved by utilizing features of the quantum well based heterostructures on metamorphic buffer. Based on this metamorphic technique two electronic devices, named high electron mobility transistors (MHEMTs) & heterojunction bipolar transistors (MHBTs) are the areas of interest now-a-days...
Soft errors caused by ionizing radiation have emerged as a major concern for current generation of CMOS technologies and the trend is expected to get worse. Soft error rate (SER) measurement, expressed as number of failures encountered per billion hours of device operation, is time consuming and involves significant test cost. The cost stems from having to connect a device-under-test to a tester for...
