Abstract

A cluster-based secure strategy for hierarchical wireless heterogeneous sensor networks(HWHSNs) is proposed. The HWHSNs consist of some normal sensor nodes and heterogeneous sensor nodes that have greater power and transmission capability than other normal nodes. Their structure is a two-layer structure. The upper layer consists of all cluster heads, namely heterogeneous sensor nodes, and the lower layer consists of all normal sensors managed by their corresponding cluster heads. All kinds of sensor nodes are evenly distributed respectively in entire sensing area. The two-dimension sensing area is divided into a number of clusters, each of which contains four small squares called cells. The pairwise keys between all kinds of nodes are set up through employing the concept of the overlap key sharing and the random key pre-distribution scheme. Analysis and comparison show this scheme improves the security for HWHSNs, enhances the connectivity for HWHSNs, and prolongs the lifetime of HWHSNs by employing some heterogeneous nodes.
