Method of Detecting Denial of Service Attacks in WSNs While Optimizing Network Life Span

Abstract

The miniaturization of sensors, the increasingly low cost, the wide range of types of sensors available as well as the wireless communication medium used, allow sensor networks to develop in several fields of application. Sensor networks can be very useful in many applications when it comes to collecting and processing information from the environment. In addition, today these micro devices are among the main components of the Internet of Things (IoT) paradigm. Several constraints block the proper functioning of the wireless sensor network. These limitations motivate a large part of research problems in the field of wireless sensor networks (WSNs), in particular the energy and security constraints that are a fundamental problem. In sensor networks, it is essential that each sensor node and base station can verify that the data received was sent by a trusted sender and not by an adversary who tricked legitimate nodes into accepting fake data. False data can change the way a network might be predicted. Data integrity should be maintained. The data must not change and the precise data must reach the end of the user. In this paper, we tackle security problems in WSN. And we focus on protection against so-called “denial of service” attacks. So the aim of the work presented is therefore to propose a set of effective detection and reaction methods to denial of service attacks, while saving or distributing the energy consumption of the sensors as well as possible to extend the network's operating time as much as possible.
