Transform-Based Distributed Data Gathering [PDF]

IEEE Transactions on Signal Processing, 2010
A general class of unidirectional transforms is presented that can be computed in a distributed manner along an arbitrary routing tree. Additionally, we provide a set of conditions under which these transforms are invertible. These transforms can be computed as data is routed towards the collection (or sink) node in the tree and exploit data ...
