Wireless networks are increasingly used to serve real-time flows. We provide an overview of an emerging theory on real-time wireless communications and some of its main results. This theory is based on a model that jointly considers the delay bounds and throughput requirements of clients, as well as the unreliable and heterogeneous nature of wireless links. This model can be further extended in several...
Analog to digital converters are an important system building block, as an interface between analog and digital world. Parallel comparator type (flash) ADCs is used in high speed, low resolution applications. This paper presents the characterization analysis of CMOS flash ADCs under Threshold inverter technique for different resolutions, the effect of the VLSB (step size) of the comparator on the...
This paper presents performance analysis of different Fast Adders. The comparison is done on the basis of three performance parameters i.e. Area, Speed and Power consumption. Further, we present a design methodology of hybrid carry lookahead/carry skip adders (CLSKAs). This modified carry skip adder is modeled by using both fix and variable block size. In conventional carry skip adder, each block...
This paper proposes AREA-MAC, a medium access control (MAC) protocol for wireless sensor networks (WSNs). AREA-MAC reduces latency and energy consumption of nodes by using low power listening (LPL) with short preamble messages. Other protocols like B-MAC use long preamble messages that cause higher latency, energy consumption, and control overhead on nodes. AREA-MAC provides a reasonable trade-off...
We demonstrate the generation of high-quality entangled photon pairs in the 1310-nm O-band. Using an ultra-stable source design, we produce polarization entanglement with 97.5% fidelity as characterized via coincidence basis tomography.
The recently standardized IEEE 802.15.4 protocol is emerging as a basic building block for wireless sensor network applications by providing many appealing features, such as low power, low cost, low data-rate, and simplicity. However, when treating applications with strict timeliness, energy, and bandwidth requirements several problems arise, triggering the need of a solution for an efficient twinning...
