Abstract
Abstract This article provides an overview about selected security and dependability solutions for wireless sensor networks. The proposed concepts have been recently developed in the European projects UbiSecSens, Sensei and WSAN4CIP. The main focus of this article is on securing convergecast traffic, securing multicast as well as aggregation providing in-network resilience for real-time wireless sensor networks. All the discussed solutions have in common that, besides an adequate security level, key design aspects are energy efficiency and a small memory footprint.
