Symbol error rate on fading self-interference channel in full-duplex
Springer Science and Business Media LLC - Tập 67 - Trang 477-483 - 2017
Fei Wu, Donglin Liu, Youxi Tang
In-band full-duplex (FD) is being considered as a promising technology for the next generation wireless communication systems. In this paper, the performance of orthogonal frequency division multiplexing (OFDM) modulation system with different symbol duration and the code spreading system with different spreading sequence lengths under time-varying self-interference (SI) channel in FD mode is inve...... hiện toàn bộ
Implementation and efficiency analysis of composite DNS-metric for dynamic server selection
Springer Science and Business Media LLC - Tập 71 - Trang 1-18 - 2018
Drazen Tomic, Drago Zagar, Goran Martinovic
User requirements for a high availability and fast response time of network services require placing more than one server for accessing particular network service, often using multiple communication links and locations. Dynamic Server Selection (DSS) is a new DNS method for the optimal server selection of a multiple available network service that allows dynamic selection of a server on the client ...... hiện toàn bộ
Developing network configuration management database system and its application—data federation for network management
Springer Science and Business Media LLC - Tập 52 - Trang 993-1000 - 2011
Hiroshi Yamada, Takeshi Yada, Hiroto Nomura
The numbers of network devices, software, and services to be managed are continuously increasing. Therefore, it has become difficult to manage a network using traditional approaches that rely on human monitoring. A configuration management database (CMDB) is useful for network managers for performing all network management activities. It is an accurate and trusted repository. We show the work in p...... hiện toàn bộ
An analytic traffic model with adaptive QoS control in an unreliable wireless sensor network
Springer Science and Business Media LLC - Tập 53 - Trang 415-424 - 2013
Shensheng Tang
An analytic traffic model is developed for an unreliable wireless sensor network. We model the dynamics of traffic flow from the source node through a set of intermediate nodes to the sink node by using single-server queues. These single-server queues with finite buffers are linked in tandem. To analyze the performance of the sensor network, we decompose the tandem queuing network into individual ...... hiện toàn bộ
Performance analysis of multi-hop token relay strategy in HF networks
Springer Science and Business Media LLC - Tập 83 Số 3 - Trang 277-287 - 2023
Pooriya Gholipoor, Mohammad Hossein Madani, Sajad Poursajadi
Performance optimization of tethered balloon technology for public safety and emergency communications
Springer Science and Business Media LLC - Tập 75 - Trang 235-244 - 2019
S. H. Alsamhi, F. A. Almalki, Ou Ma, M. S. Ansari, M. C. Angelides
This paper investigates the potential of a tethered balloon network architecture deployed as part of public safety networks and emergency communications. Tethered balloon technology has been evolving as a powerful and promising technology for improving public safety and for saving people’s lives. As such, it enables accomplishment of unique and specific missions for temporary events such as natura...... hiện toàn bộ
A new approach for designing and implementing ADF equalization for 5G frequency selective channel based on two operating phases of LS and RLS algorithms
Springer Science and Business Media LLC - Tập 77 - Trang 543-562 - 2021
A. Y. Hassan
In this paper, a new approach is proposed for implementing an adaptive decision feedback equalizer (ADFE) for the 5G channel. The proposed equalizer works in two phases. In the first phase, a least-squares (LS) algorithm with a variable-length training sequence is used to estimate the coefficients of the channel and the equalizer. In the second phase, the recursive least-squares algorithm estimate...... hiện toàn bộ
gTFRC, a TCP friendly QoS-aware rate control for DiffServ Assured Service
Springer Science and Business Media LLC - Tập 33 - Trang 3-21 - 2006
Emmanuel Lochin, Laurent Dairaine, Guillaume Jourjon
This study addresses the end-to-end congestion control support over the DiffServ Assured Forwarding (AF) class. The resulting Assured Service (AS) provides a minimum level of throughput guarantee. In this context, this article describes a new end-to-end mechanism for continuous transfer based on TCP-Friendly Rate Control (TFRC). The proposed approach modifies TFRC to take into account the QoS nego...... hiện toàn bộ
Information transmission based on network coding over wireless networks: a survey
Springer Science and Business Media LLC - Tập 65 - Trang 551-565 - 2016
Olfa Ben Rhaiem, Lamia Chaari
Network coding (NC) for wireless local area network has received a lot of attention from researchers. It replaces the traditional methods of video erasure protection. The principal of NC is to combine several packets together before their transmission. Thus, NC is able to provide higher throughput, reliability and efficient transmission. Up to now, many works have been done to ensure the advantage...... hiện toàn bộ
On the limitation of fluid-based approach for Internet congestion control
Springer Science and Business Media LLC - Tập 34 - Trang 3-11 - 2006
Do Young Eun
Fluid models have been the main tools for Internet congestion control. By capturing how the average rate of each flow evolves, the fluid model proves to be useful as it predicts the equilibrium point to which system trajectory converges and also provides conditions under which the convergence is ensured, i.e., the system is stable. However, due to inherent randomness in the network caused by rando...... hiện toàn bộ
