ABSTRACT
Basis Pursuit (BP) finds a minimum 1-norm vector z that satisfies
the underdetermined linear system Mz = b, where the matrix M
and vector b are given. Lately, BP has attracted attention because of
its application in compressed sensing, where it is used to reconstruct
signals by finding the sparsest solutions of linear systems. In this
paper, we propose a distributed algorithm to solve BP. This means
no central node is used for the processing and no node has access to
all the data: the rows of M and the vector b are distributed over a set
