Localized DoS Attack Detection Architecture for Reliable Data Transmission Over Wireless Sensor Network

Abstract

Due to the scattered nature of WSNs, resource constraints, the radio link for multi-hop communications and their remote area deployment, WSNs are exposed to several security attacks that can affect overall network performance. Therefore, security is the primary concern for improving the network performance, by detecting internal attacks to ensure the functionality of WSNs. For example, using a compromised node like an adversary could perform any attack pretending as a normal node of the network to acquire all the information is known as internal attack. Denial of Service (DoS) attacks are a set of attacks initiated by individual node or group of nodes by exploiting the transmission to deny other nodes from legitimate access to resources such as bandwidth, computing power and operating system. Some of the DoS attacks like selective forwarding and hello flood attacks are the most common attacks in WSN, which increases the resource scarcity among all the nodes in the network. In the proposed mechanism, an approach has been developed to resolve the issue of DoS attacks by implementing terminologies such as Intruder Detection System, authenticating nodes with a key mechanism and retracing routing path as an evasive action from the path involved with the victim node in the form of an internal attacker in the network. The primary focus of this proposed work is to contribute secure and reliable data transmission over source and destination by resolving DoS attack.
