Utilization of energy consumption metric to detect black hole attacker in dsr routing protocol

Abstract

A Mobile Adhoc Network (MANET) is a self-organized system comprised of multiple mobile wireless nodes. They do not require the existing network infrastructure. Autonomous telescopes can change freely and inadvertently in a network that can establish a dynamic network temporarily, and these networks can often change their appearance. Due to the openness in network topology and the absence of centralized administration in management, MANET is vulnerable to attacks from malicious nodes. Therefore, security is a major issue in MANET, which drastically reduces network performance. Several trust parameters such as packet delivery ratio, packet dropping ratio, etc are used for detecting the malicious node attack in MANET. Among these, this paper uses the energy as the trust parameter for detecting the malicious node. The energy reduction ratio differs from the normal node and attacker node in MANET. Hence, the main aim of this paper is to find the Normal Energy Reduction Ratio (NERR) and Attacker Energy Reduction Ratio (AERR). These two values are used for differentiating the normal node and attacker node in MANET. For routing, this paper uses the Dynamic Source Routing (DSR) Protocol.
