A simulation-optimization approach for the stochastic discrete cost multicommodity flow problem
( Taylor and Francis Ltd. , 2020 , Article)This article addresses a variant of the Discrete Cost Multicommodity Flow (DCMF) problem with random demands, where a penalty is incurred for each unrouted demand. The problem requires finding a network topology that ... -
An exact approach for the multicommodity network optimization problem with a step cost function
( EDP Sciences , 2019 , Article)We investigate the Multicommodity Network Optimization Problem with a Step Cost Function (MNOP-SCF) where the available facilities to be installed on the edges have discrete step-increasing cost and capacity functions. ... -
An Autonomous Packet Transmission Strategy for Opportunistic Wireless Sensor Networks
( Hindawi Publishing Corporation , 2012 , Article)We consider a wireless sensor network that comprises a single hop between the sensor nodes and the central controller node with multiple antennas. In this system model, we concentrate on the single-beam opportunistic ... -
ENHANCING THE PERFORMANCE AND SECURITY OF ANONYMOUS COMMUNICATION NETWORKS
(2022 , Dissertation)With the increasing importance of the Internet in our daily lives, the private information of millions of users is prone to more security risks. Users data are collected either for commercial purposes and sold by service ... -
Network Coding versus Replication Based Resilient Techniques to Mitigate Insider Attacks for Smart Metering
( SAGE publications , 2015 , Article)The main focus of this paper is the resilience of communication protocols for data gathering in distributed, large scale, and dense networks. In our previous work, we have proposed the resilient methods based on random ... -
A Survey on Energy Harvesting and Integrated Data Sharing in Wireless Body Area Networks
( SAGE publications , 2015 , Article)Wireless body area networks (WBANs) are important branches of wireless sensor networks (WSNs). They promise unobtrusive ambulatory health monitoring for real-time updates of patients' medical records that have aroused ...
