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

In this paper we describe a novel strategy for carrying out lookups in Chord-based peer-to-peer (P2P) networks, wherein nodes are assumed to behave selfishly. This is in contrast to the traditional lookup schemes, which assume that nodes cooperate with each other and truthfully follow a given protocol in carrying out resource lookups. The proposed scheme also provides efficient and natural means for preventing free-riding problem in Chord without requiring prior trust relationships among nodes. In addition, we evaluate the performance of Chord for providing routing service in a network of selfish nodes and prove that it has good structural properties to be used in uncooperative P2P networks.
