Clustering is an important method for extending the network life of each node in wireless sensor networks. Owing to the untrustworthy environment, these nodes unintentionally sacrifice their energy and lost their life which is a major challenge and ...

This study aimed at analysing intercarrier interference (ICI) of filter bank multicarrier signals which are made by hyperbolic fractional Fourier transform, depend on optimum order of transform for the Internet of Things applications. Calculation of ICI ...

This study investigates codes in the term‐rank metric. These codes can be used to correct crisscross errors in a (M×N) matrix. These errors can be found in memory chip arrays, in magnetic tape recordings, or in the parallel‐channel system with ...

In this study, the authors explore a wireless network consisting of multiple smart terminals relying on multi‐mode in the presence of an eavesdropper, where the eavesdropper may be deployed to wiretap the wireless communications deliberately. In general, ...

This study considers a downlink power consumption problem for unmanned aerial vehicles (UAVs)‐assisted wireless communications, in which UAVs are used as aerial base stations to provide service for the ground users and equipped with a directional antenna ...

In this study, joint users selection and beamforming based on users positioning are proposed for enabling non‐orthogonal multiple access (NOMA) in the millimetre‐wave (mmWave) transmissions. In the proposed scheme, the mmWave users are arranged in ...

Massive multiple‐input multiple‐output (MIMO) systems with hundreds of correlated antennas at base station are capable of offering abundant spatial resources. When spatial‐domain modulation is applied to these systems, the spatial modulation (SM) using ...

In this study, the authors analyse the downlink (DL) performance of dynamic‐time division duplexing (D‐TDD) enabled millimetre‐wave (mmWave) network with different base station (BS) heights using a channel model that incorporates the effect of shadowed ...

Hybrid precoding, combining the digital and analogue precoding, is a key enabler to reach a compromise between system performance and hardware complexity in millimetre wave (mmWave) massive multiple‐input multiple‐output (MIMO) systems. Most previous ...

This study introduces an accurate design and optimisation of a passive optical code division multiple access (OCDMA) network encoder using the coupled cavity waveguide (CCW) as an optical delay line. Such CCW has the capability of providing more time ...

Internet of things (IoT) is one of the modern technologies, developing existing cellular communication networks to the emerging fifth‐generation technology. The traffic modelling of IoT applications is different from the recommended traffic modelling of a ...

A novel direction‐of‐arrival (DOA) estimation method based on electronically controlled beam scanning leaky‐wave antenna (LWA) combined with estimation of signal parameters via rotational invariance techniques (ESPRIT) algorithm is proposed. In order to ...

This study proposes a scheme to realise secure orthogonal frequency‐division multiplexing (OFDM) wireless communication between two full duplex nodes—node A and node B. If node A wants to send secret messages to node B, node A and node B transmit the ...

Wireless sensor network (WSN) consists of spatially distributed miniature size and autonomous nodes along with batteries as a power source. The major bottleneck of WSN is efficient energy utilization. The energy consumption for transmission of signals ...

The need to maximise energy efficiency (EE) for device‐to‐device (D2D) communication has become an urgent necessity for the fifth‐generation wireless networks. In this study, the power allocation problem is considered for the cellular system underlaid ...

Breaking down botnets has always been a big challenge. The robustness of command and control (C&C) channels is increased, and the detection of botmaster is harder in peer‐to‐peer (P2P) botnets. In this study, the authors proposed a probabilistic method to ...

In this study, the problem of adaptive modulation and frame length (AMFL) is investigated in long‐term evolution for railway (LTE‐R) communication system. By considering the effect of frame length, a novel AMFL strategy based on Moore state machine (MSM) ...

Holographic data storage (HDS) can access data in a short amount of time and can also quickly transmit data because HDS records and reads data in units of pages. Thus HDS is regarded as a promising candidate for future optical recording storage systems. ...

The Cognitive Radio (CR) plays a key role in identifying free bandwidths in the Radio Frequency (RF) spectrum. High‐speed Analog‐to‐Digital Converters are normally applied for spectrum sensing of sideband signals providing several raw data for digital ...

There are two main classes of decision fusion methods, namely hard decision fusion (HD) and soft decision fusion (SD), in which the number of bits transmitted by each local sensor to the fusion centre (FC) is always same, namely one bit in HD and n (n ≥ 2)...
