NeXt generation/dynamic spectrum access/cognitive Radio Wireless Networks: A Survey

by Ian F. Akyildiz, Won-Yeol Lee, Mehmet C. Vuran, Shantidev Mohanty - COMPUTER NETWORKS JOURNAL (ELSEVIER , 2006
"... Today's wireless networks are characterized by a fixed spectrum assignment policy. However, a large portion of the assigned spectrum is used sporadically and geographical variations in the utilization of assigned spectrum ranges from 15% to 85% with a high variance in time. The limited availabl ..."

Abstract—The growing use of Wireless Sensor Networks (WSNs) to accomplish tasks with strict requirements in terms of secrecy and reliability is increasingly attracting the interest of malicious users, thus incrementing the demand for more secure and dependable WSN implementations. Such necessity is directly reflected in the growing need for tools and techniques to ease the design, assessment and validation of security solutions suited for WSN deployments. Initially, WSNs were mainly considered as stand-alone systems but the emerging Internet of Things (IoT) vision is fostering a deeper integration of WSNs as a part of the Internet, hence making holistic approaches and re-use of existing solutions more effective also concerning security. In order to cope with this evolving scenario, this paper proposes a tool to support penetration testing of actual WSN deployments based on the 6LoWPAN family of protocols, considered one of the main building blocks of the IoT paradigm. The feasibility of WSN penetration testing as an approach to tackle IoT security is demonstrated through a practical proof-of-concept developed by extending the well-known Metasploit Framework targeting actual WSN deployments based on 6LoWPAN.
