On a common sensor node platform (Telos) we sample RSSI with high frequency during packet reception. We find that a packet collision (RF interference) often manifests as a measurab...
Researchers use the PlanetLab testbed for its ability to host experimental applications in realistic conditions over the public besteffort internet. Such applications form overlays...
While several approaches have been proposed in literature for improving the performance of wireless packet data networks, a recent class of approaches has focused on improving the...
—Virtualized cloud-based services can take advantage of statistical multiplexing across applications to yield significant cost savings to the operator. However, achieving simila...
Unlike other diversity-based approaches, N-variant systems thwart attacks without requiring secrets. Instead, they use redundancy (to require an attacker to simultaneously comprom...
