Outage analysis of hybrid FSO/RF systems based on finite-state Markov chain modeling
( IEEE , 2014 , Conference Paper)In this paper, we analyze the outage probability of a hybrid free-space optical/radio-frequency (FSO/RF) communication system with soft-switching. In soft-switching approach, either one of the links or both links can be ... -
Outage analysis of selective cooperation in underlay cognitive networks with fixed gain relays and primary interference modeling
( IEEE , 2012 , Conference Paper)Selective cooperation is a well investigated technique in non-cognitive networks for efficient spectrum utilization and performance improvement. However, it is still a nascent topic for underlay cognitive networks. Recently, ... -
Outage optimal resource allocation for two-hop multiuser multirelay cooperative communication in OFDMA upstream
( IEEE , 2011 , Conference Paper)We investigate an outage optimal adaptive resource allocation scheme for the upstream of two-hop OFDMA based decode-and-forward cooperative relay systems. The objective of this work is to design resource allocation strategy, ... -
Outage performance of cooperative systems under IQ imbalance
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Article)In this contribution, we investigate the outage performance of OFDM-based Decode and Forward (DF), Amplify and Forward (AF) and Controlled DF (CDF) cooperative systems under IQ Imbalance (IQI). In particular, tractable and ... -
Outage performance of incremental relaying networks with OFDM subcarriers mapping schemes
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)The scarcity of radio resources coupled with the high data rate demands in the last few years, induced incremental relaying techniques one of the most promising technologies. This is simply because it allows reaping spatial ... -
Outage performance of multi-hop hybrid FSO/RF communication systems
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)In this paper, five scenarios are considered for the realization of a multi-hop hybrid free-space optical/radio frequency (FSO/RF) communication system with decode-and-forward (DF) relaying, and analytical outage probability ... -
Outage performance of OFDM Ad-hoc routing with and without subcarrier grouping in multihop network
( IEEE , 2012 , Conference Paper)In this contribution, we investigate Decode and Forward (DF) OFDM Ad-hoc Routing strategy with bottleneck maximization. We derive the exact outage probability and diversity order for the different scenarios: with and without ... -
Outage performance of OFDM-based relaying systems under IQ imbalance
( IEEE , 2013 , Conference Paper)In the presence of different IQ imbalance (IQI) levels in the different nodes of a cooperative system, it becomes necessary to investigate the effect of each imbalance parameter on the performance. In this contribution, ... -
Outage Performance of UAV-Assisted Relaying Systems with RF Energy Harvesting
( Institute of Electrical and Electronics Engineers Inc. , 2018 , Article)In this letter, we propose an UAV-based relaying system with energy harvesting functionality. In particular, we assume that this system is operated in urban communication environments, where the channel between the UAV and ... -
Outlier detection approaches based on machine learning in the internet-of-things
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)Outlier detection in the Internet of Things (IoT) is an essential challenge issue studied in numerous fields, including fraud monitoring, intrusion detection, secure localization, trust management, and so on. Conventional ... -
Outlier edge detection using random graph generation models and applications
( Springer , 2017 , Article)Outliers are samples that are generated by different mechanisms from other normal data samples. Graphs, in particular social network graphs, may contain nodes and edges that are made by scammers, malicious programs or ... -
Output Feedback Fault-Tolerant Control of Heterogeneous Multi-Agent Systems
