Detection and Prevention of UDP Protocol Exploiting and Smurf Attack in WSN Using Sequential Probability Ratio Test Algorithm

Wireless sensor networks (WSNs) have gained popularity in diverse areas such as military surveillance, patient monitoring, traffic control, environmental and structural monitoring. However, the use of wireless technology also introduces new security threats that need to be addressed. In this paper, the author will discuss these threats and propose solutions to ensure the security and integrity of WSNs. As WSNs rely on radio frequencies for communication, they are more susceptible to hindrances compared to wired systems. DOS attacks have the ability to be launched into multiple layers of the OSI model, encompassing the network, transport, and application layers. In this research paper, the proposed algorithm was implemented using the COOJA simulator. Consequently, the algorithm successfully identified the attacker, initiated a UDP attack. UDP attack launched by the attacker, leaded to the prevention of the SMURF attack and ensured network security. This study concludes with a method for detecting protocol exploitation and smurf attacks in WSNs, along with information on how to use it and how to handle such cases.
