Towards Source Localization in a Complex Environment With a Low Number of Sensors

The pervasiveness of communication infrastructures allows to envisage the implementation of multi-functional facilities able to perform both communication and sensing functions. In this framework, one interesting application is the exploitation of opportunistic sensors, working at communication frequencies, for indoor surveillance tasks. As a contribution toward this goal, this study analyzes the problem of performing an accurate and reliable localization of a source in a partially known scenario using a very low number of sensors.
