A finite state hidden markov model for predicting multistage attacks in cloud systems
( IEEE , 2014 , Conference Paper)Cloud computing significantly increased the security threats because intruders can exploit the large amount of cloud resources for their attacks. However, most of the current security technologies do not provide early ... -
Comparison of relaying strategies for cooperative diversity systems with adaptive modulation
( IEEE , 2009 , Conference Paper)In this paper, we propose several relay selection schemes for cooperative diversity systems with adaptive transmission. The proposed schemes are based on dual-hop relaying with multiple relays. We analyze the performance ... -
Frequency of Parathyroid Hormone Assessment in the Evaluation of Hypercalcemia. A Comparison Between Patients With and Without a History of Malignancy in a 20-year Dataset of 20,954 Patients
( SAGE Publications Ltd , 2021 , Article)Background: The purpose of this study was to evaluate whether a prior diagnosis of malignancy affected the assessment of parathyroid hormone (PTH) in hypercalcemic patients and whether the rate of this assessment changed ... -
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 ... -
Performance analysis of general order selection in decentralized cognitive radio networks
( IEEE , 2014 , Conference Paper)In this paper, we consider an underlay secondary network comprising of K transmitter-receiver pairs sharing the spectrum of a primary network, which is divided into n non-overlapping frequency bands (subchannels). Each ... -
A predictive strategy for lifetime maximization in selective relay networks
( IEEE , 2009 , Conference Paper)Two algorithms based on an energy conserving dynamic transmit power threshold are proposed for improving the lifetime in relay networks utilizing selective relay strategies with amplify-and-forward (AF) relays. the lifetime ... -
To Relay or Not To Relay in Cognitive Radio Sensor Networks
( IEEE , 2014 , Article)A recent investigation on MAC layer in cognitive radio networks proposed the primary packet relaying by the secondary node maintaining an extra queue used for this particular addable functionality. Nevertheless, relaying ...
