The H-LU factorization is a very important algorithm for the construction of robust H-matrix preconditioners for BEM and FEM problems.This paper describes how the construction … WebTherefore, we propose a Hierarchical Matrix Decomposition-based Signcryption (HMDS) scheme, which adopts the cluster-based hierarchical architecture illustrated as in Figure 1. There are three layers, base station (BS), cluster head layer, and intracluster layer. Usually, the WSN consists of a few clusters and a BS.
