An analytical study of cache invalidation algorithms in mobile environments

Kwong Yuen Lai, Zahir Tari, Peter Bertok

Caching is commonly used to improve the performance of mobile computers. Due to the limitations of wireless networks (e.g. low bandwidth, intermittent connectivity), ensuring the…

Content quality assessment and acceptance testing in location‐based services

Artem Katasonov, Jari Veijalainen, Markku Sakkinen

In this paper, we develop and evaluate an approach to assessing the content quality in a location‐based service (LBS). The proposed approach, instead of assessing the quality in…

Sub‐grid based key vector assignment: A key pre‐distribution scheme for distributed sensor networks

R. Kalindi, R. Kannan, S.S. Iyengar, A. Durresi

Security in sensor networks is more important than traditional networks as they are deployed in hostile environments and are more prone to capture. Trusted third party…

A reverse channel call admission control scheme based on total received power for CDMA systems supporting integrated voice/data services

Wei Li, Hang Chen, Dharma P. Agrawal

In code‐division multiple‐access (CDMA) systems, the number of mobile users that each cell can support is limitedby the total received power or interference received at each base…
