AN IMPROVEMENT OF NETWORK SECURITY IN MOBILE AD HOC NETWORKS USING NOVEL THREAT DETECTION AND MITIGATION TECHNIQUES

MANETs are important as intermediary routers, yet they are an infrastructure-free communication network that falls under autonomous devices. There are two types of MANET routing protocols: proactive and reactive. Proactive routing protocols are known as OLSR, whereas reactive routing methods are known as AODV [1] and DSR [2]. Compared to proactive OLSR [3,], reactive AODV and DSR are more efficient and scalable due to their reduced routing expense. AODV and DSR were designed with the assumption that all nodes should trust each other and that there should be no malicious spying between nodes in the network. As a result, the existence of any node poses security difficulties. Also, bandwidth is vital in network communication because wireless links are considerably better than wired links. Noise, interference from other signals, and fading could all damage wireless link communications
