Secure Localization for Wireless Sensor Networks using Range- Independent Methods

摘要

Wireless Sensor Networks (WSNs) are envisioned to be integrated into our everyday lives, enabling a wealth of commercial applications such as environmental and habitat monitoring, disaster relief and emergency rescue operations, patient monitoring, as well as military applications such as target detection and tracking. These applications are facilitated by the collaborative processing of the physical properties monitored by the sensors, such as temperature, light, sound, humidity, vibration, acceleration, or air quality. The majority of the localization techniques that are proposed for WSNs are designed to operate in a benign environment with no security threats. However, WSNs may be deployed in hostile environments and operating unsupervised, and hence, are vulnerable to conventional and novel attacks aimed at interrupting the functionality of location-aware applications by exploiting the vulnerabilities of the localization scheme. In this chapter, we study the problem of enabling nodes of a WSN to determine their location even in the presence of malicious adversaries. This problem will be referred to as Secure Localization. We consider secure localization in the context of the following design goals: (a) decentralized implementation, (b) resource efficiency, and (c) robustness against security threats.
