The availability of secret keys is a precondition for the use of many security solutions and protocols. However, securely assigning such keys to nodes is a challenging task in the context of wireless sensor networks. In this paper we present a novel solution for a secure key assignment in wireless sensor networks that can be used during the initial configuration of nodes or for an ad-hoc key assignment...
Impulse radio ultra wide band (IR-UWB) is a promising technology to address wireless sensor network (WSN) constraints. However, existing network simulation tools do not provide a complete WSN simulation architecture, with the IR-UWB specificities at the physical (PHY) and the medium access control(MAC) layers. In this paper, we propose a WSN simulation architecture based on the IR-UWB technique. At...
