Detecting black-hole attacks in WSNs using multiple base stations and check agents

摘要

Wireless Sensor Networks (WSNs) consist of multiple sensors distributed in a certain geographic area. The goal of using WSNs is to monitor certain phenomena such as; environmental or physical. The nodes in WSNs transmit data through a wireless network that lacks infrastructure, which makes those networks exposed to security threats. One of those security threats is the black-hole attack which can be considered as a Denial of Service (DoS) attack that is very difficult to detect. In this attack, the intruder re-programs a set of nodes in the target network to prevent the received packets from being sent to the destination. Such changes to the sensors results in high delay and low throughput. Therefore, we propose in this paper a novel technique for detecting black-hole attacks in WSNs using multiple base stations and check agents.
