Security Technique against Power Exhausting Attacks in WSN

Abstract

Resistant to malware threats is the major difficult problem in WSN. Furthermost important challenge was Rejection of sleep attacks because power is the extremely valuable source for the network. Such type of attacks depletes sensor node power supplies and reduces sensor lifespan. For data transmission between wireless nodes, the most important consideration is power. A DoS attack on a WSN is being contemplated, with the attack affecting the battery life of the devices connecting to the network. The major role of a DoS attack is to reduce the availability of connected devices by shortening their battery life. The connected devices are kept on inactive status which decreases battery life and influences battery management. A novel approach will be used in the proposed work for power management of the connected devices to enhance the battery lifetimes. When either of the connected devices senses low power or is not in operation, it defaults to sleep mode to save battery power. The framework is made vulnerable to such attacks using the methodology discussed, and it also works to detect such attacks and nodes. The description and in-depth understanding of energy exhausting attacks and tactics is a major consideration in the work presented. The RSSI value, in conjunction with route information, is used in the proposed technique to identify malicious nodes and ensure network security. The cluster mechanism is also considered for better and improved performance.
