UML modeling of cross-layer attack in wireless sensor networks

Abstract

The openness of wireless communication and the unattended nature of sensor node deployment make it easy for an adversary to launch various attacks on wireless sensor networks. Cross-layer attack aims to achieve better attack effects, conceal attack behavior more better, reduce the cost of attack by using information from multiple protocol layers, or initiate attack at multiple layers cooperatively. There are now different understandings about cross-layer attack. In this paper, the definition of cross-layer attack is proposed and several cases of attacks are presented. In order to better understand their behaviors, the cases of cross-layer attack are modeled by utilizing unified modeling language, which helps to build more secure wireless sensor networks.
