Research and Development of Delay-Sensitive Routing Tensor Model in IoT Core Networks

open access: yesSensors, 2021
In the article, we present the research and development of an improved delay-sensitive routing tensor model for the core of the IoT network. The flow-based tensor model is considered within the coordinate system of interpolar paths and internal node ...

Gossiping with interference in radio ring networks [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
In this paper, we study the problem of gossiping with interference constraint in radio ring networks. Gossiping (or total exchange information) is a protocol where each node in the network has a message and is expected to distribute its own message to ...

Ranging and multipath‐enhanced device‐free localisation with densely‐meshed ultra‐wideband devices

open access: yesIET Microwaves, Antennas & Propagation, 2023
Device‐free localisation (DFL) is a prominent example of radio sensing and radio frequency (RF)‐based passive localisation. RF‐based passive localisation approaches determine the position of a non‐cooperative user based on the user's impact on radio ...

Regional autonomous security cooperative spectrum sensing method based on trust value

open access: yesIET Communications, 2023
In order to solve the problems of spectrum resource shortage, low spectrum utilization and shadow effect, a regional autonomous security cooperative spectrum sensing (CSS) method based on trust value is proposed to address the vulnerability of CSS ...

Design and characteristic analysis of hybrid OFD–LFM–PC waveforms in the MIMO radar

open access: yesThe Journal of Engineering, 2019
In this study, a new set of hybrid orthogonal frequency division–linear frequency modulation–phase coded (OFD–LFM–PC) waveforms are proposed to improve the detection performance of multiple-input-multiple-output (MIMO) radars.
