On the delay/throughput-security tradeoff in wiretap TDMA networks with buffered nodes
( IEEE , 2019 , Article)In this paper, we investigate the tradeoff between security and throughput and between security and queuing delay in wiretap time-division multiple access (TDMA) networks. We derive a simple relationship, characterized by ... -
On the Design of a Relay-Assisted Network
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)A relay network composed of a source, a set of relays, and a destination is considered. A queueing framework is proposed, in which each node maintains a buffer to store its incoming traffic. An optimization-based formulation ... -
On the Design of Bit-Slice Processors
( Qatar University , 1988 , Article)In the past decade, fixed instruction microprocessors have evolved from 4 bits to 32 bits. Their compact design and relative low cost have made them very popular with design engineers. Their use extends into a lot of ... -
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 ... -
On the detection and estimation of correlated signal using circular antenna arrays
( IEEE , 2011 , Conference Paper)This paper presents the design and analysis of smart antenna systems used for the detection and estimation of correlated radio signals encountered in multipath environments using circular antenna arrays. The MUSIC algorithm ... -
On the detection of Kernel-level rootkits using hardware performance counters
( Association for Computing Machinery, Inc , 2017 , Conference Paper)Recent work has investigated the use of hardware perfor- mance counters (HPCs) for the detection of malware run- ning on a system. These works gather traces of HPCs for a variety of applications (both malicious and ... -
On the development of flywheel storage systems for power system applications: A survey
( IEEE , 2012 , Conference Paper)Energy storage systems cannot be considered energy sources but having the ability of storing and discharging energy. They have a vital rule in the reliability and power quality of power systems. There are several energy ... -
On the distributed binary consensus algorithm in wireless sensor networks
( IEEE , 2013 , Conference Paper)We consider the binary consensus problem over the wireless sensor networks (WSN), where each node of the network initially observes one of two states and the aim of each node is to decide which one of the two states was ... -
