Executive Summary

In this paper, the authors consider a mobile cooperative network that is tasked with building a map of the spatial variations of a parameter of interest, such as an obstacle map or an aerial map. They propose a new framework that allows the nodes to build a map of the parameter of interest with a small number of measurements. By using the recent results in the area of compressive sensing, they show how the nodes can exploit the sparse representation of the parameter of interest in the transform domain in order to build a map with minimal sensing. The paper allows the nodes to efficiently map the areas that are not sensed directly. To illustrate the performance of the proposed framework, they show how the nodes can build an aerial map or a map of obstacles with sparse sensing.
