A biologically-inspired embedded monitoring network system for moving target detection in panoramic view
EURASIP Journal on Wireless Communications and Networking - Tập 2013 - Trang 1-7 - 2013
An embedded monitoring network system is based on the visual principle of compound eye, which meets the acquirements in field angle, detecting efficiency, and structural complexity of panoramic monitoring network. Three fixed wide-angle cameras are adopted as sub-eyes, and a main camera is installed on a high-speed platform. The system ensures the continuity of tracking with high sensitivity and a...... hiện toàn bộ
Performance analysis of wireless-powered cognitive radio networks with ambient backscatter
EURASIP Journal on Wireless Communications and Networking - Tập 2019 - Trang 1-13 - 2019
Ambient backscatter is a promising wireless communication technique where low-power users communicate with each other without any dedicated power source. These communicating users transmit their information by reflecting ambient radio-frequency (RF) signals. In this paper, we propose an ambient backscatter communications-assisted wireless-powered underlay cognitive radio network (CRN). The propose...... hiện toàn bộ
Opportunistic routing with in-network aggregation for duty-cycled WSNs with delay requirements
EURASIP Journal on Wireless Communications and Networking - Tập 2014 - Trang 1-16 - 2014
This paper proposes an opportunistic routing protocol for wireless sensor networks that works on top of an asynchronous duty-cycling medium access control (MAC) protocol. The proposed protocol is designed for applications that are not real-time but still have some requirements on packet delay. The main idea is that if a packet has time to spare, it can wait on a node hoping that it can be aggregat...... hiện toàn bộ
Diversity-multiplexing tradeoff analysis and optimization for OFDM-based multihop relaying systems
EURASIP Journal on Wireless Communications and Networking - Tập 2012 - Trang 1-11 - 2012
In this article, we consider a single-antenna orthogonal frequency division multiplexing-based multihop relaying system over frequency selective fading channels employing subcarrier grouping and linear constellation precoding at the source, and linear detection at the destination. We derive closed-form expressions of the diversity-multiplexing tradeoff relation, and propose the optimal precoder de...... hiện toàn bộ
Design and experimental evaluation of a low-complexity spatial combiner for LTE distributed antenna systems
EURASIP Journal on Wireless Communications and Networking - Tập 2013 - Trang 1-8 - 2013
This article presents a distributed antenna system (DAS) architecture for small-cell base stations (BTSs), whereby cooperation between the DAS infrastructure and the BTS allows for an increase in performance compared to conventional systems, while at the same time keeping complexity and cost at low levels. Specifically, the article investigates the improvements in uplink physical layer performance...... hiện toàn bộ
Research on geometric algebra-based robust adaptive filtering algorithms in wireless communication systemsAbstract Noise and interference are the two most common and basic problems in wireless communication systems. The noise in wireless communication channels has the characteristics of randomness and impulsivity, so the performance of adaptive filtering algorithms based on geometric algebra (GA) and second-order statistics is greatly reduced in the wireless communicati... ... hiện toàn bộ

Analysis of group paging with pre-backoff
EURASIP Journal on Wireless Communications and Networking - Tập 2015 - Trang 1-9 - 2015
Group paging can simultaneously activate hundreds of user equipments (UEs) using a single paging message. Upon receiving the group paging message, all UEs should immediately transmit their paging response messages through the random access channels (RACHs). Simultaneous channel access from a huge group of UEs may result in severe collisions of the RACHs during a very short period of time. In this ...... hiện toàn bộ

Joint resource optimization for secure transmission in cooperative CR networks
EURASIP Journal on Wireless Communications and Networking - Tập 2017 - Trang 1-8 - 2017
In this paper, we investigate the joint resource allocation to provide secure information transmission in a five-node cooperative cognitive radio network, which contains a primary transmitter (PT), a primary receiver (PR), a secondary transmitter (ST), a secondary receiver (SR), and an eavesdropper (E). To ensure the information is securely transmitted, PT and PR use a part of the power to transmi...... hiện toàn bộ
Two-hop time synchronization protocol for sensor networks
EURASIP Journal on Wireless Communications and Networking - Tập 2014 - Trang 1-10 - 2014
One of the critical middleware services for sensor networks is the time synchronization, which provides supports to different applications. Synchronization protocols used for Internet and LANs are not appropriate in the sensor networks for the high-density and limited energy resource. This paper describes two-hop time synchronization (TTS) that aims at reducing the synchronization overhead and pro...... hiện toàn bộ
