Generating and Evaluating Object-Oriented Designs for Instructors and Novice Students

Creating object-oriented designs for even simple problems of the type assigned to beginning students is a challenging task. While rules can be applied to identify key design components, multiple acceptable solutions often exist, and instructors may have different preferences for which variations are best. The paper describes a tool one...

A Ferry-Based Intrusion Detection Scheme for Sparsely Connected Ad Hoc Networks

Several intrusion detection approaches have been proposed for mobile adhoc networks. Many of the approaches assume that there are sufficient neighbors to help monitor the transmissions and receptions of data packets by other nodes to detect abnormality. However, in a sparsely connected adhoc network, nodes usually have very small number...

Optimum Signaling for MIMO-OFDM Systems With Interference

Optimum signaling is studied for Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) systems with multiple links which mutually interfere. Numerical results show that using the optimum approach for cases without interference does not always achieve system capacity. In some cases, the overall system performance is improved by forcing users to...

Distributed Power Control and Routing for Clustered CDMA Wireless Ad Hoc Networks

This paper considers a multi-hop wireless ad hoc network where all nodes share a common channel, and Code Division Multiple Access CDMA is used to facilitate concurrent transmissions. The network model consists of groups of nodes that may loosely be termed as clusters. The paper addresses the question of how...

Improving internal search and detecting cloaking

One of the problems with using search inside the enterprise is that corporate users rarely link to internal data on Web pages like users on the greater Internet do. This means that using incoming links as a way of ranking search results for relevance page rank doesn't work nearly...
