Procuring Wireless Sensor Actuator Network Security

Abstract

Wireless Sensor Actuator Networks (WSANs) are large-scale innovative networks. The dynamic, reconfigurable, and self-adjustment nature of these networks make them distinctive from rest of the networks using wireless medium for communication. This is because these networks are basically placed in hostile environments like—surveillance, forest fire detection, flood detection; it has many applications and defense is the most prominent one. Hence security forms the basis of this paper which includes attack detection and mitigation using various schemes. A vision on denial-of-service (DoS) attack and its preventive measures for WSAN are in particular. The preeminent objective of this paper is to identify various intruder attacks in WSANs and to propose a new optimal solution for the prevention of DoS attacks (flooding attack) in WSAN. There are various mechanisms to eliminate the malicious node that carry out an attack. These mechanisms are used to safe guard against intruder attacks. In this paper, we have simulated flooding attack in wireless sensor actuator networks, computed a mitigation system and tested the validity of our results.
