Driven by rapid growth in wireless demand, spectrum sharing has recently been the focus of extensive research. A common concern is how to address coexistence-related interference, especially when the involved systems operate under different protocols. In this paper, we outline a framework for exploiting full-duplex (FD) capabilities to support coexistence in a heterogeneous spectrum sharing environment...
In Wireless Sensor Networks (WSN), sensors form the network dynamically without help of any infrastructure. The accidental death of the nodes due to technical failures or death due to power exhaustion may disturb the existing coverage and connectivity of the network. In this paper, distributed coverage hole recovery algorithms for the wireless sensor networks are designed that use the vector methods...
Since the very beginning of the flash memory era, the market has been dominated by the floating gate technology. However, as floating gate flash continues along a very steep scaling path, more and more barriers start to appear, limiting further scaling possibilities of the technology. At the same time, other concepts are preparing to take over. This paper concentrates on the prospect of high-k materials...
Multi-core SoC created great opportunities to increase overall system performance while keeping the power in check but also created many design challenges that designers must now overcome. The challenge of doubling performance every two years used to drive superscalar design with more functional units running concurrently or deeper pipeline racing for highest frequency at the cost of higher power...
In this study, we fabricated in-plane thermoelectric micro-generators (4 mm times 4 mm) based on bismuth telluride thin films by using flash evaporation method. The thermoelectric properties of as-grown thin films are lower than those of bulk materials. Therefore the as-grown thin films were annealed in hydrogen at atmospheric pressure for 1 hour in a temperature range of 200 degC. to 400degC. By...
