Abstract
This paper considers the problem of fusing the statistical information gained by a distributed network of sensors. We formulate the problem as a convex feasibility problem, that is, finding a point in the intersection of finitely many closed convex sets. We then present a distributed optimization algorithm to solve the problem.
