A security architecture for wireless sensor networks environmental

The Wireless Sensors Network (WSN) is an emergent technology resulting from progress of various fields. Many applications of networks WSN are developed. In the last years, wireless sensor networks (WSNs) have gained increasing attention from both the research community and actual users. As sensor nodes are generally battery-powered devices, the critical aspects to face concern how to reduce the energy consumption of nodes, so that the network lifetime can be extended to reasonable times. As sensor networks are deployed in adversarial environments and used for critical applications. In this paper, we consider routing security in wireless sensor networks. Many sensor network routing protocols have been proposed, but very less of them have been designed 738 Bijoy Kumar Mandal et al. with security as a goal. We propose security goals for routing in sensor networks. We describe crippling attacks against all of them and suggest countermeasures and design considerations.
