“…WSNs that rely on UWB radio signals are somewhat inherently more secure, since the low output power and the short pulses of the emitted signals make their transmissions to appear as white noise from a distance (Karapistoli, Pavlidou, Gragopoulos, & Tsetsinas, 2010). Nevertheless, UWB signals could potentially be sniffed by a determined attacker located close to the transmitter (Ghose & Bose, 2011;Ko & Goeckel, 2010), enabling the latter to launch an attack against the WSN. Therefore, even this class of WSNs calls for the development of intelligent security systems that will safeguard the network's uninterrupted operation against attackers that have penetrated the first perimeter of defense.…”

Wireless sensor networks (WSNs) are gaining more and more interest in the research community due to their unique characteristics. Besides energy consumption considerations, security has emerged as an equally important aspect in their network design. This is because WSNs are vulnerable to various types of attacks and to node compromises, and as such, they require security mechanisms to defend against them. An intrusion detection system (IDS) is one such solution to the problem. While several signature-based and anomaly-based detection algorithms have been proposed to date for WSNs, none of them is specifically designed for the ultra-wideband (UWB) radio technology. UWB is a key solution for wireless connectivity among inexpensive devices characterized by ultra-low power consumption and high precision ranging. Based on these principles, in this paper, we propose a novel anomaly-based detection and location-attribution algorithm for cluster-based UWB WSNs. The proposed algorithm, abbreviated as ADLU, has dedicated procedures for secure cluster formation, periodic re-clustering, and efficient cluster member monitoring. The performance of ADLU in identifying and localizing intrusions using a rule-based anomaly detection scheme is studied via simulations.

Cooperative jamming, a potential supplement can be used to improve physical layer based security by transmitting a weighted jamming signal to create interference at the eavesdropper. The secrecy rate is derived for cooperative jamming technique in terms of network throughput. We have analysed the effect of Aloha protocol with cooperative jamming on the secrecy capacity of large scale network. To implement cooperative jamming with Aloha protocol a transmitter can be considered as a source or as a friendly jammer with the massage transmission probability p. We observed that an optimum level of security can be achieved for a specific value of jammer power using cooperative jamming and at the moderate value of massage transmission probability p using cooperative jamming with Aloha protocol.Index Terms-Aloha, friendly jammer, physical layer security, path loss exponent, secrecy capacity.
