Stealthy attacks in MANET to detect and counter measure by ant colony optimization

Abstract

MANET (Mobile Ad Hoc Network) is the active wireless network which can produce communication less connections in which every node can perform as a router. Every node in the MANET is responsible for dynamically creating other nodes for communication. Protection is an important examine for the wireless and wired network communications in MANET. The achievement of MANET (mobile ad hoc networks) strappingly depends upon people’s assurance in its sanctuary. Though, uniqueness of MANET poses both opportunity and challenges in the accomplishment of security purpose, like authentication, privacy, access, availability, integrity, non-repudiation, and control. The malicious node presence is being a major challenge in MANET for designing the vigorous security solution which can defend the MANET from different routing attacks. We have categorized the existing security services and security threats in this mobile ad hoc network paper. The proposed approach gives a better solution in the achievement of present security threats in MANET. Based on monitoring system a guard node is recommended in this paper through which every activity occurred inside the network can be constantly monitored. If there is any abnormal action of Stealthy attack occurred inside the network then the Guard node collects and forwards the abnormal information toward the source node. In this guard node an algorithm based on Ant Colony optimization is deployed to recognize the threats which are present in the MANET’s network. This proposed system detects the stealthy attack and also resists the attackers from the network. Therefore, this approach makes the enhancement in the network packet delivery and its performance ratio, etc.
