The authors present an overview of new multiple access schemes based on a combination code division and multicarrier techniques, such as code-division (MC-CDMA), direct sequence CDMA (multicarrier DS-CDMA), multitone (MT-CDMA).
This paper focuses on the use of satellite communication systems for support Internet Things (IoT). We refer to IoT paradigm as means collect data from sensors or RFID and send control messages actuators. In many application scenarios, actuators are distributed over a very wide area; in some cases, they located remote areas where not served by terrestrial access networks and, consequence, becomes paramount importance Remote (IoRT). The enabling factors IoRT through are: 1) interoperability...
This paper presents the advantages and disadvantages of a multicarrier code-division multiple-access (MC-CDMA) system. The transmitter/receiver structure and, bandwidth transmitted signal spectrum are compared with those conventional direct-sequence (DS) CDMA system, an MC-CDMA design method, how to determine number subcarriers length guard interval is discussed. bit error rate (BER) lower bounds for DS-CDMA systems derived their equivalence theoretically demonstrated. Finally, BER...
The pervasiveness of wireless technology has indeed created massive opportunity to integrate almost everything into the Internet fabric. This can be seen with advent Things and Cyber Physical Systems, which involves cooperation number intelligent devices provide services. Fairness amongst these is an important issue that analysed from several dimensions, e.g., energy usage, achieving required quality services, spectrum sharing, so on. article focusses on viewpoints while looking at fairness...
In the last few years Internet of Things (IoT) has seen widespreadapplication and can be found in each field. Authentication accesscontrol are important critical functionalities context IoTto enable secure communication between devices. Mobility, dynamicnetwork topology weak physical security low power devices IoTnetworks possible sources for vulnerabilities. It ispromising to make an authentication access control attack resistant andlightweight a resource constrained distributed IoT...
IoT is going to be an established part of life by extending the communication and networking anytime, anywhere. Security requirements for will certainly underline importance properly formulated, implemented, enforced security policies throughout their life-cycle. This paper gives a detailed survey analysis embedded security, especially in area IoT. Together with conventional solutions, highlights need provide in-built device itself flexible infrastructure dynamic prevention, detection,...
Millimeter-wave (mm-wave) communications and nonorthogonal multiple access (NOMA) are two important techniques to achieve high data rates in fifth-generation (5G) ultradense networks (UDNs). Due interference that is intentionally added during the superpositioned transmissions with NOMA, an additional power budget required maintain target block error rate (BLER). This necessitates consideration of new approaches ensure efficiency NOMA systems. In this article, we show can be implemented using...
The IEEE “Tactile Internet” (TI) Standards working group (WG), designated the numbering 1918.1, undertakes pioneering work on development of standards for TI. This paper describes WG, its intentions, and developing baseline standard associated reasoning behind that touches a further already initiated under scope: 1918.1.1 “Haptic Codecs TI.” 1918.1 aim to set framework act as foundations TI, thereby also serving basis developed TI within WG. discusses aspects such created architecture,...
We review new multiple access schemes based on a combination of code division and multi-carrier (also known as OFDM: orthogonal frequency multiplexing) techniques, such (MC-CDMA), multicarrier DS-CDMA multitone CDMA (MT-CDMA). discuss their advantages disadvantages, present some computer simulation results the down-link bit error rate (BER) performance in selective slow Rayleigh fading channel. Code OFDM have drawn lot attention field wireless personal multimedia communications because need...
The basis for any air interface design is how the common transmission medium shared between users (i.e., multiple access scheme). underlying method all mobile radio systems FDMA. performance of TDMA and CDMA has been subject to vigorous debate, without definitive conclusions. This article gives an overview worldwide research standardization activities related schemes third-generation communications IMT-2000 UMTS.
Internet of Things (IoT) concept enables the possibility information discovery about a tagged object or person by browsing an internet addresses database entry that corresponds to particular active RFID with sensing capability. It is media for retrieval from physical world digital world. With cooperative wireless communication, node entities can increase their effective quality service (QoS) via cooperation. In developing countries death rates due lack timely available medical treatments are...
Results from propagation measurements, conducted in an indoor office environment at 2.4, 4.75, and 11.5 GHz, are presented. The data were obtained small clusters of six using a coherent wideband measurement system. channel characteristics for the three frequencies compared by evaluating path loss, rms delay spread, coherence bandwidth. An analytical model evaluation bit-error rate (BER) stationary frequency selective is developed binary phase shift keying (BPSK) receiver, based on complex...
The ever-increasing growth of user demand, the limitations third generation wireless mobile communication systems, and emergence new broadband technologies on market have brought researchers industries to a thorough reflection fourth generation. Many prophetic visions appeared in literature presenting 4G as ultimate boundary without any limit its potential, but practical terms not giving design rules thus definition it. In this article we give pragmatic derived from user-centric methodology...
The advent of Internet Things (IoT) has boosted the growth in number devices around us and kindled possibility umpteen applications. One major challenges realization IoT applications is interoperability among various deployments. Thus, need for a new architecture-comprising smart control actuation-has been identified by many researchers. In this paper, we propose Distributed Internet-like Architecture (DIAT), which will overcome most obstacles process large-scale expansion IoT. It...
This article discusses recent standardization efforts related to cognitive radio focusing on the work of IEEE Standards Coordinating Committee 41, formerly known as 1900. Some important tasks be performed by CR community also are presented. These will expedite introduction devices market while promoting a fair use scarce resources. avenues for using currently available standards rapid deployment devices, such ISO standards, discussed.
