Multi-objective sensor placement using the effective independence model (SPEM) for wireless sensor networks in structural health monitoring
Elsersy, Mohamed; Ahmed, Mohamed Hossam; Elfouly, Tarek Mohamed; Abdaoui, Abderrazak ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)This paper studies the optimal placement problem in structural health monitoring (SHM) using wireless sensor networks (WSN). This problem is formulated as a refined multi-objective optimization problem with various constraints ... -
On the distributed binary consensus algorithm in wireless sensor networks
Abderrazak, Abdaoui; El Fouly, Tarek Mohamed ( 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 ... -
Optical mode division multiplexing for secure Ro-FSO WLANs
Amphawan, Angela; Chaudhary, Sushank; Elfouly, Tarek; Abualsaud, Khalid ( American Scientific Publishers , 2015 , Article)The widespread deployment of various wireless radio access systems in public areas poses acute issues in frequency assignment. Radio-over-free-space-optics (Ro-FSO) technology enhances spectral efficiency and may pave the ... -
TOSSIM and distributed binary consensus algorithm in wireless sensor networks
Abdaoui, Abderrazak; El-Fouly, Tarek M. ( Academic Press , 2014 , Article Review)In this paper, we present distributed binary consensus algorithm over the wireless sensor networks (WSN) in the presence of faulty nodes. We assume that each fault occurs during the execution of an algorithm on a sensor ... -
