A THREAT ANALYSIS ALLOWING PROGRESS IN THE SECURITY OF WIRELESS HETEROGENEOUS SENSOR NETWORKS

Wireless heterogeneous sensor networks are of considerable importance. They allow the detection of information coming from inaccessible or hostile areas, the surveillance, control and permanent monitoring of several events in the environment. Because of the irresponsible behavior of some people, the operation of these systems is unfortunately exposed to attacks degrading their performance. A large part of researchers are interested in the security of these systems and are trying to develop solutions that detect and identify these attacks. Some used an intrusion detection scheme, others used rules and key management to detect and identify malicious nodes. In this paper, we present an analysis of the procedures pursued to defend against hackers and a new method of combating attacks. This reinforces the security system of wireless heterogeneous sensor networks.
