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.

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.

In this paper we describe a novel pricing strategy for carrying out lookups and obtaining data in peer-to-peer (P2P) networks with selfish nodes. Both the resource provider and intermediate nodes that assist in routing of lookup messages are appropriately compensated so as to cover their cost of providing service. This is in contrast to the traditional lookup schemes, which assume that data is freely available, and intermediate nodes selflessly cooperate and truthfully follow a given protocol in carrying out resource lookups. The proposed scheme provides efficient and natural means to prevent free-riding problem in P2P networks, and does not require prior trust relationships among nodes. Moreover, unlike other schemes it does not rely on any centralized entity or require specialized trusted hardware at each node.
