Sensor Networks

Although sensor networks has not been the focus of my research. I have worked on a couple of problems. The more recent one was node localization from an incomplete and approximate distance matrix. Nodes within a certain distance detect each other with high probability; and those beyond are detected with very low non-zero probability. Exploiting the low rank of this approximate distance matrix, we use MDS-Localize to locate the nodes. Previously I have conducted a study of digital signal processing in sensor network domain.

(The picture has nothing to do with sensors but me and Ja are trying to network☺)
