Managed Containers For Increased Cyber-Resilience, Xavier J. Merino Aguilera
Managed Containers For Increased Cyber-Resilience, Xavier J. Merino Aguilera
Theses and Dissertations
Traditional defense mechanisms are no longer adequate in protecting critical infrastructure and mission critical systems. These systems require to be always-on-always-connected. High availability and data integrity become crucial to deliver their mission. Unable to guarantee uncompromisable security and given that systems will inevitably be attacked, we must change our goals to guarantee mission survivability, the ability of the system to fight through the attack. Previous work has been done to increase availability and integrity using virtual machines. We move away from virtual machines towards Linux containers and implement resiliency strategies to guarantee stateful system recovery after an attack. The goal …
The Impact Of Different Propagation Environments On The Performance Of Wireless Sensor Networks, Abdallah Mubark Aldosary
The Impact Of Different Propagation Environments On The Performance Of Wireless Sensor Networks, Abdallah Mubark Aldosary
Theses and Dissertations
This dissertation presents a methodology for evaluating the performance of wireless sensor network (WSN) protocols in different propagation environments. To create this methodology, practical RF propagation models that include many of the substantial features of different propagation environments are utilized, and radio energy models for different propagation environments are developed. Accurate environment-specific radio frequency (RF) propagation models should be utilized in order to improve the overall process of decision-making during pre-deployment of WSNs, to facilitate the deployment of the WSN, and to enhance the battery efficiency of sensing nodes so that the network lifetime can be prolonged. The investigating of …

Theses and Dissertations
In order to tackle the problem of network connectivity and sensing coverage in random placement of sensor nodes over an area of interest, this research presents an optimization and visualization framework for characterization and prediction of optimal deployments of large-scale wireless sensor networks (WSNs). This study presents efficient image processing algorithms for classification of deployment terrain in order to optimize deployment and connectivity coverage with required minimum number of nodes and transmission power. It reports formation of efficient models for WSN signal propagation under different terrain conditions. The study describes the developmental approach of the WSN optimization framework and visualization …
