Wireless Sensors Networks (WSN) monitoring : application to secure interoperability. (Monitorage des réseaux des capteurs sans fils (WSN) : application à l'interopérabilité sécurisée)

Abstract

Wireless Sensors Networks (WSN) monitoring Application to secure interoperability by: Raul Armando Fuentes-Samaniego The denominated “Internet of Things” (IoT) has been getting relevance in both public and research communities. The main reason is that on 2011, the number of “objects” connected to the Internet surpassed the number of humans online, and is expected that for 2020, the number of objects exceeds the amount of 20 billion. Because of the high number of heterogeneous platforms that composed the IoT, our interest is centered around the Wireless Sensors Networks (WSN), which are composed by hundred, or even thousands, of small devices with constrained resources (small amount of memory, small power processor, and small power supply) that collect one or more type of data. Almost all the research conducted to date relies on standardizing the communication protocols, ameliorating the performance, optimizing the resource consumption, etc. Security has been relegated to a second plane, due mainly to the low resources available on the sensors. However, the data collected in many scenarios can be highly sensitive, e.g. when the sensors collect health parameters, driving plates, biometrical data from pedestrian, etc. The data must be stored in a safe way and must be transmitted in a safe approach from the origin to the destiny, in a similar way than in traditional networks. The work developed in this dissertation defines mechanisms to guarantee the safety of the communication between sensors, following especially the well-known HTTP Secure (HTTPS) protocol of traditional networks. And also providing native tools for the monitoring of the communication, in order to validate these mechanisms directly on the network.
