This paper introduces a novel iterative algorithm which is capable of achieving the distributed average consensus in a finite amount of time. This algorithm exploits the possibility of storing information received from neighboring nodes at each iteration. Moreover, we propose an adaptation to the distributed average consensus problem of the Tagged and Aggregated Sums (TAS) algorithm, which we introduced in a previous paper for the distributed confidence region evaluation. The performance of both algorithms is investigated through simulation and compared with state-of-the-art approaches.

While today we rely only on the representation of the outdoors, the mapping of indoors is mainly a part of the traditional SLAM problem where robots discover the surrounding and perform self-localization. Nonetheless, robot deployment prevents from a large diffusion and fast mapping of indoors and, further, they are usually equipped with laser and vision technology that fail in scarce visibility conditions. To this end, a possible solution is to turn future personal devices into personal radars as a milestone towards the automatic generation of indoor maps using massive array technology at millimeter-waves, already in place for communications. In this application-oriented paper, we will describe the main achievements attained so far to develop the personal radar concept, using ad-hoc collected experimental data, and by discussing possible future directions of investigation.
