On the Trade-Off Between User-Location Privacy and Queried-Location Privacy in Wireless Sensor Networks
Download2009
Harms, Janelle, Vogt, Ryan, Nascimento, Mario
Technical report TR09-07. By eavesdropping on a user's query in a sensor network, an adversary can deduce both the user's location and his/her area of interest. In many domains it is desirable to guarantee privacy of both places. Relying on the principle of k-anonymity, we propose an effective...

Mobile objects can be equipped with sensors enabling them to collect data, as well as answer queries remotely and in real-time. For that, one needs to be able to effectively route queries from a base station to the queried object in an efficient way, i.e., with minimum energy-cost and/or minimum...

Alencar, Romulo, Nascimento, Mario, Brayner, Angelo
Technical report TR09-05. It is a well known fact that minimizing energy consumption in Wireless Sensor Networks (WSNs) is crucial for its usability; and minimizing the flow of data is one way to achieve that. Most WSN models assume the existence of a base station where query results could in...

PalmIRA: Information Retrieval in the Palm of Your Hand
2002
Technical report TR02-16. Personal Digital Assistants (PDAs) are becoming increasingly popular and with this increase in popularity comes the increased number of applications that store textual data within the PDA. The research area of information retrieval has developed a number of effective and...

Performance Evaluation of Optimistic Cache Consistency Algorithms for Web-based Electronic Commerce Applications
Download2000
Technical report TR00-15. Caching is a simple and effective way to provide faster access to information on the Internet, and it has been used effectively to improve the performance of E-commerce servers. However, there is a growing concern by today's Web service providers to ensure that the...
