Coverage properties of clustered wireless sensor networks
(ACM, 2010-08)
This article studies clustered wireless sensor networks (WSNs), a realistic topology resulting from common deploymentmethods.We study coverage in naturally clustered networks of wireless sensor nodes, as opposed to WSNs ...
Experimental investigation of the impact on TCP traffic by hidden video-tagged UDP traffic
(IEEE, 2017)
This paper investigates the impact of video-tagged UDP traffic on best-effort TCP traffic in an experimental setup with a novel observation approach. Our setup consists of three 802.11ac nodes in a hidden node topology, ...
Outage performance of mixed RF-FSO systems over DGG and nakagami-m channels
(IEEE, 2020-12)
In mixed RF (radio frequency)-FSO (free space optical) systems, the FSO link is used for backhauling while RF is used for wireless access. In many practical deployment scenarios especially in urban environments, more than ...
Experimental validation of a novel RLL code for visible light communication
(IEEE, 2020)
Flicker arising in visible light communication (VLC) system is typically mitigated by run-length-limited (RLL) codes. The IEEE 802.15.7 standard proposes RLL codes according to the modulation type and data rate. In this ...
UAV-based FSO communications for high speed train backhauling
(IEEE, 2019)
In line with the increasing number of high speed train (HST) commuters and their demand for mobile data, railways operators expore means of providing high speed on-board wireless access. The data from all train cars are ...
Statistical modeling of propagation channels for Terahertz band
(IEEE, 2017)
Digital revolution and recent advances in telecommunications technology enable to design communication systems which operate within the regions close to the theoretical capacity limits. Ever-increasing demand for wireless ...
ViLDAR: a novel speed estimation system using visible light in vehicles
(IEEE, 2017)
In this paper, we introduce Visible Light Detection and Ranging (ViLDAR): a novel speed estimation system that utilizes visible light variation during a known time difference. The use of light emitting diodes (LED) in ...
Fast-decodable MIMO HARQ systems
(IEEE, 2015-05)
This paper presents a comprehensive study on the problem of decoding complexity in a Multi-Input Multi-Output (MIMO) Hybrid Automatic Repeat reQuest (HARQ) system based on Space-Time Block Codes (STBCs). We show that there ...
Auction based spectrum trading for cognitive radio networks
(IEEE, 2013-06)
In this letter, we consider the shared used model in cognitive radio networks and design a spectrum trading method to maximize the total satisfaction of the Secondary Users (SUs) and revenue of the Wireless Service Provider ...
Performance of multiuser scheduling in free space optical systems over atmospheric turbulence channels
(IEEE, 2015-10)
In this study, the authors consider a multiuser multiple-input multiple-output (MU-MIMO) free space optical (FSO) communication system and investigate the performance of various scheduling protocols which provide different ...
