This present paper, a 3 transistor XNOR gate is proposed. The proposed XNOR gate is designed using CADENCE EDA tool and simulated using the SPECTRE VIRTUOSO at 180 nm technology. The proposed results are compared with the previous existing designs in terms of power and delay. It is observed that the power consumption is reduced by 65.19 % for three transistor XNOR gate and 48.11% for eight transistor...
With the features provided by wireless mesh networks (WMN) and the increasing number of users, the Quality of Service (QoS) has become essential to support multimedia applications. In addition, employing the multichannel approach has led to the improvement of the network performance. However, selecting a path with the maximum available bandwidth to transmit data from the source to the destination...
The current study is dedicated to the investigation of stability issues occurring in switching power converters with non-ideal feedback circuitry. The interaction of nonlinear effects caused by the introduction of delay in the control circuitry of the compensated boost converters is studied by means of complete bifurcation diagrams, exploiting discrete-time modeling approach. The effectiveness of...
Social connections among network users have been well investigated as an additional opportunity in network design, such as in routing strategies and trusted networking. This paper presents a paradigm shift that explores the design and performance analysis of combining social links jointly with communication links to support message delivery in wireless networks. In a combined social and communication...
Analog Comparator is designed to compare two analog inputs and outputs a logical signal indicating which of the inputs is greater or lesser. Comparators, being an essential building block of most high speed devices like Analogue to Digital Converters, are one of the most important components used in signal processing and communication systems. Also it plays a challenging role in high speed mixed signal...
Wireless sensor networks (WSNs) have increasingly become the viable means of distributed sensing and control for a wide array of applications. The energy-sensitive sensor nodes in these systems are often augmented by an energy harvesting device, allowing for continuous operation. The drawback, however, is that the availability of communication resources is uncertain. Decentralized optimization is...
Covert channels are used for information transmission in a manner that is not intended for communication and is difficult to detect. The authors have proposed and explored the way to counter the leakage of information via covert channels by introducing additional random delays before packets' sending. The main topic of the research is the case when the capacity of the covert channel without error...
Sharing Transmission Opportunity period (TXOP) technique is recently defined by IEEE 802.11ac to allow simultaneous downlink transmissions.
