Interconnects are integral part in the chip design which plays a major role in circuit performance in DSM technology. Due to the presence of parasitic such as Resistance, Capacitance components, signal degradation and delayed problems may occur. Now days because of technological advances, number of nodes increasing in circuits, there by introducing more parasitic in multi nodes which will effect on...
Cognitive Radio ad hoc network is a sort of wireless network. Cognitive radios have the ability to sense the wireless medium. Routing is the major research area and ensuring quality-of-service (QoS) is a challenging problem. This paper proposes a neighbor node discovery mechanism based delay aware routing protocol in order to provide QoS in such network. Primary QoS metrics such as throughput and...
Scanning attack is usually the precursory step to attack a network by which adversaries gather significant information of the network and employ it to discover the vulnerabilities and save their precious time. Recently, researchers have proved that adversaries can scan a SDN network utilizing packets response time difference. In this paper, a probability-based delay scheme is introduced to combat...
In this paper, we propose a simple yet effective parametric adaptive filter (PAF) and demonstrate its excellent performance in acoustic echo cancellation applications. Specifically, the proposed PAF decomposes an adaptive filter into three components: a normalized finite impulse response filter, a gain factor and a time-shift factor. With a novel update scheme for the PAF, these three components can...
In Software defined networks (SDNs), controller placement is an important problem which will affect the performance of the network directly. At present, there have been some studies on the controller placement problem in SDN from different aspects such as delay, capacity, reliability and load balance. In this paper, the controller placement problem is discussed from the aspect of delay and load balance...
In the research the load balancing routing model in Time-Sensitive Networks is proposed. The novelty of the solution is a type of optimality criterion, the use of which minimizes the circuit delays. The proposed solution is compromise in terms of computational implementation as compared to the previously known models, in which the equality of the circuit delays of packets were considered as limitations,...
Performance modeling and optimization for on-chip interconnects in resistive RAM (ReRAM) arrays are presented for two memory design technologies of 1T1R and cross-bar arrays. Different memristor characteristics, cell structures and subarray design schemes are investigated to minimize the overall delay and energy-delay product.
This paper presents a low power noise tolerant comparator design for arithmetic circuits. Instead of using domino logic, this paper uses a modified domino logic style. This logic uses semi-domino logic style and some extra footer transistors which lead to minimize power dissipation and noise of the comparator. The new comparator is compared with the basic domino comparator in terms of noise tolerance,...
A 3 MHz, 48W Boost converter with high speed and high accuracy Peak Current Control Unit (PCCU) is presented. The Boost controller IC adopts a novel PCCU consisting of a fully differential open-loop operational transconductance amplifier (OTA) and a trans-impedance amplifier (TIA), which can minimize the delay and error of the whole control loop. In the PCCU, the compensated output of error amplifier...

In this paper, 802.11ah and BLE technologies are evaluated and compared in a home automation scenario. The selected use case includes battery powered sensors, which generate traffic, and mains powered actuators, which consume traffic, connected through a central gateway...
Wireless Multimedia Sensor Networks (WMSNS) are composed of a number of sensors which usually the most important data generated by them are video data. According to massive amounts of data, congestion control is essential for quality preservation of the video data. Quality of video data depends on low latency and high reliability. In this paper, an approach for congestion control is proposed. In the...
Reverse proxies are key performance elements of a content distribution network (CDN) and operate as intermediaries between client and upstream (or origin) server traffic. A typical reverse proxy server aims to distribute user workload, more or less equally, among multiple upstream servers. To keep the pace with the growing demand for content, CDNs regularly expand their capacity by adding extra upstream...
It is expected that billions of devices will be connected with each other through the Internet of Things (IoT). Different aspects of IoT, such as security, have been extensively explored in the literature. However, the research focuses on how to identify and secure the IoT. We believe that it is very important to investigate how the IoT infrastructure will response when a huge amount of data is generated...
This work presents a study concerning the impact of Cloud Radio Access Network and virtualisation techniques in an operator's network, namely in terms of the necessary number of storage and processing nodes, and the links in between, taking increasingly network constraints into account (e.g., latency) as well as deployment ones (e.g., service area, deployment strategy, and expected proliferation of...
This paper focuses on the current state of voice over Internet protocol in wireless mesh networks. Mesh network formation is dynamic, unpredictable and self-healing. Thus, voice traffic transportation in such networks requires special care in each mesh node and in the overall mesh network infrastructure so as to prevent the voice quality from degrading, possibly to the point where voice over Internet...
The low voltage clocked regenerative comparator provides maximum speed and power efficiency and is thus required for implementing area efficient and ultra low-power analogue to digital converters (ADCs).
