A Novel Sensor Localization Scheme by Mobile Actors [Poster Abstract]
Résumé
We propose a localized sensor localization scheme making full use of controlled mobility of a location-aware actor and the connectivity of the sensor network. It contains two new algorithms: a unscented particle filter (UPF) based localiza- tion algorithm and an actor mobility scheduling algorithm. The former is an application of UPF. It enables sensor self- localization using received signal strength indicator and ac- tor position. The latter models actor mobility scheduling as traveling salesman problem and aims at fully localized net- work and minimized time delay. Navigated by sensors, the actor depth-first traverse a local minimum spanning tree of a connected 3-dominating set of the network.
