A Probabilistic Packet Filtering-Based Approach for Distributed Denial of Service Attack in Wireless Sensor Network

摘要

Wireless sensor networks (WSNs) are widely used networks that have lured attention of varied research fields due to their numerous ranges of applications. They have limited energy and power consumption, memory, communication, and computation capabilities. They are also distributed and randomly deployed. Due to the above-listed features, they are prone to various security threats and attacks. Distributed denial of service (DDoS) attack is one among them. These attacks aim at flooding the victim with abundant packets so as to exhaust its resources and cripple its capacity to receive desired packets and give its response accordingly. The network becomes congested and the victim becomes either unresponsive leading to denial of service or its response gets delayed. In this paper, we propose a mitigation mechanism that will curb the attempts of the attackers aiming to flood the WSN so as to cause denial of service with multitude of packets within a time span.
