Modeling Critical Infrastructure Khaled Abdelghany SMU - May 2005

Problem 1 On the Optimal Deployment of Heterogeneous Surveillance Devices in Critical Infrastructure Networks Collaborators: Hesham El-Rewini, SMU

Heterogeneous set of surveillance Devices Reliability Lifespan Mobile capability Energy scheduling capability

Dynamic Infrastructure Networks Networks: Different criticality levels Different vulnerability levels 57 t = 1 t = 2 t = 3t = 4t =

Objective Function: Maximizing Network Coverage Maximize: Assign high-weight observations to surveillance devices with high reliability

Problem 2 Modeling Pedestrians Dynamics in Crowded Facilities using Cellular Automata Collaborators: Ahmed Abdelghany UoA Hani Mahmassani UoM

Cellular Automata The environment of interest is divided into cells. Individuals are moving between these cells according to microscopic behavioral rules.
