The Department of Electrical and Computer Engineering (ECpE) contains two focuses. The focus on Electrical Engineering teaches students in the fields of control systems, electromagnetics and non-destructive evaluation, microelectronics, electric power & energy systems, and the like. The Computer Engineering focus teaches in the fields of software systems, embedded systems, networking, information security, computer architecture, etc.

History
The Department of Electrical Engineering was formed in 1909 from the division of the Department of Physics and Electrical Engineering. In 1985 its name changed to Department of Electrical Engineering and Computer Engineering. In 1995 it became the Department of Electrical and Computer Engineering.

Abstract

We investigate the problem of provisioning light-paths for dynamic advance reservation (AR) requests in all-optical wavelength division multiplexed networks. We propose a two-phase novel routing, slot, and wavelength assignment (RWSA) technique called Non-Continuous Single-Slot Advance Reservation (NC-SSAR). We propose two NC-SSAR heuristics, one with only lightpath segmentation (SEG-NC-SSAR) and the other with lightpath segmentation and lightpath switching (LPS-NC-SSAR). We briefly discuss three baseline RWSA heuristics and compare them with the proposed heuristics. Through extensive simulations, we show that the proposed NC-SSAR heuristics can solve the RWSA problem more effectively and efficiently by providing significantly lower blocking and reducing the overall signaling in the network by minimizing the number of lightpath switches, compared to the baseline RWSA heuristics.
