Zone Based Hybrid Layered Protocol for Mobile Ad hoc Networks

Mobile Ad-hoc Networks (MANETs) are a subset of wireless ad-hoc networks that typically consist of an end-to-end Link Layer (LL) ad-hoc network with a routable networking environment. Whereas mobile networks have a central controller, MANETs are hop-to-hop, self-arrangement, and self-configured networks. Because ad-hoc networks have unique vulnerabilities that current IDS solutions cannot address, the solutions might not always be enough. Un-forward capacity nodes are one of the primary attack kinds in the network. They pose as intermediary nodes on a route to specific targets and drop any packet that passes through them. The mechanism is cooperative, therefore the protocol cooperates to analyze and discover malicious nodes in MANETs in a reliable way. In this study, they suggest black-hole assaults as an analysis approach to detect malicious nodes. In order to validate our created method, we used the Modified-Zone based Hierarchical Link State (M-ZHLS) hybrid routing protocol with mobile nodes in Network Simulations 2 (NS2). When mobility speed and topology size change, it is found that the Zone based Hierarchical Link State (ZHLS) routing protocol has a very good detection rate for black holes and malicious nodes, a lower average delay, and an increased packet delivery ratio.
