IoT Anti-Jamming Strategy Using Game Theory and Neural Network
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
The internet of things (IoT) is one of the most exposed networks to attackers due to its widespread and its heterogeneity. In such networks, jamming attacks are widely used by malicious users to compromise the private and ...
Throughput maximization via adjusting packet size of a buffered cognitive radio user
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper, we investigate a cognitive scenario with one secondary user and one primary user. Users are assumed to be buffered terminals. Each user has certain arrival rate with certain packet size. We propose a scheme ...
The effect of additional statistical side information on multiple antenna spectrum sensing
(2012 , Conference Paper)
In this paper, we consider the problem of multiple antenna spectrum sensing in Cognitive Radios (CR) when some or all parameters are unknown. The Generalized Likelihood Ratio (GLR) test is the convectional method to solve ...
On the design of relay-assisted primary-secondary networks
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
The use of N cognitive relays to assist primary and secondary transmissions in a time-slotted cognitive setting with one primary user (PU) and one secondary user (SU) is investigated. An overlapped spectrum sensing strategy ...
Optimization of collaborative spectrum sensing with limited time resource
(
Springer Verlag
, 2015 , Conference Paper)
In this paper, Cognitive Radios (CRs) collaborate in spectrum sensing to detect random signals corrupted by Gaussian noise. Our analysis is based on a limited time resource assumption. This implies that the time resource ...
Joint interference cancellation and dirty paper coding for cognitive cellular networks
(2011 , Conference Paper)
Downlink communication in a cellular network with a cognitive (secondary) cell is considered. In our model, the base station of the cognitive cell knows the messages of the other cell non-causally. We propose a new ...
On the degrees of freedom of the cognitive broadcast channel
(2011 , Conference Paper)
Cognitive broadcast channel, where two multiantenna transmitters communicate with their respective receivers, is considered. One of the transmitters is said to be cognitive (secondary) as it is assumed to know the messages ...
Towards Information Theoretic Interpretation of Practical Ciphers
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
In spite of the wide spread of practical crypto- systems and ciphers nowadays, they still lack a unique metric to measure the secrecy level they provide. Their strength is measured in an ad-hoc way by exposing them to ...
Securing IoT Cooperative Networks Using Energy Harvesting.
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
An energy efficient and secure Internet of Things (IoT) healthcare system is proposed in this paper. By exploiting spatial diversity, energy harvesting and physical layer security techniques, the proposed approach secures ...
Non-uniform quantized distributed sensing in practical wireless rayleigh fading channel
(
Springer Verlag
, 2015 , Conference Paper)
In this paper, we study non-uniform multilevel quantization problem in cognitive radio networks (CRNs). We consider a practical collaborative spectrum sensing (CSS) scenario in which secondary users (SUs) cooperate with ...
