Résumé
In a wireless sensor network (WSN), sensors are typically deployed in an area in order to collect events related to one or more sensing features such as temperature, humidity, light, pressure, magnetic, accelerometer, acoustic activity, seismic movements, etc. The sensors communicate with each other to relay events to a Sink node or a Base Station that communicates with the network operator. Since the most critical feature in sensor networks is the hardship of its energy resources because each sensor node has initial low resources in terms of energy and it is not often possible to replace batteries during network operations. Moreover, equipped with a small processor generally associated to a small storage unit, sensors often operate without human assistance, and could be deployed in open and hostile environments. Therefore, wireless sensor networks are subject to various types of threats, vulnerabilities and attacks which are carried out in order to disclosure sensitive information, to disrupt network operations and to exhaust the batteries of the nodes and then to reduce their lifetimes, and consequently that of the network. In this paper, we will try to give an overview study of security issues and solutions in WSN.
