Monitoring techniques have been deeply studied in wired networks using gossip and hierarchical approaches. However, when applied to a MANET, several problematics arise. We present a hybrid distributed monitoring architecture for MANETs. We get inspired of gossip-based and hierarchicalbased algorithms for query dissemination and data aggregation. We define gossip-based mechanisms that help our virtual hierarchical topology to complete the data aggregation, and then ensure the stability and robustness of our approach in dynamic environments. We propose a fully distributed monitoring protocol that ease the nodes communications. We evaluate our approach by using NS3 and Docker.
International audienceWireless Mesh Networks (WMN) are growing rapidly in the research community due to their numerous applications and shared services. A feature in this kind of networks is the any-to-any connectivity, which opens the network for diverse kinds of attacks. These attacks generate extra traffic that possibly carries unauthorized intrusions. Our proposal, the IBW Framework, includes an approach for security in WMN detecting and mitigating the attacks through the use of non-relational databases for the data correlation and the dissemination of intrusion information among the nodes in WMN to reduce the amount of attacks in short time. Data correlation is done from the log data of servers and distributed Intrusion Detection & Prevention Systems (IDSs & IPSs) using syslog information with a particular format. Intrusion Prevention Systems can be implemented with any kind of solution, in our case we proposed iptables. Finally, a Case Study is presented, using the OLSR routing protocol and Brute Force attacks comparing our proposal with an open source blocking tool Fail2Ban. The whole scenario is being emulated in Dockemu to generate similar attack patterns for the result compariso
The mobile ad-hoc networks (MANETs) represent a broad area of study and market interest. They provide a wide set of applications in multiple domains. In that context, the functional and non-functional monitoring of these networks is crucial. For that purpose, monitoring techniques have been deeply studied in wired networks using gossip-based or hierarchical-based approaches. However, when applied to a MANET, several problematics arise mainly due to the absence of a centralized administration, the inherent MANETs constraints and the nodes mobility. In this paper, we present a hybrid distributed monitoring architecture for mobile ad-hoc networks in context of mobility pattern. We get inspired of gossip-based and hierarchical-based algorithms for query dissemination and data aggregation. We define gossip-based mechanisms that help our virtual hierarchical topology to complete the data aggregation, and then ensure the stability and robustness of our approach in dynamic environments. Further, we propose a fully distributed monitoring protocol that ease the nodes communications. We evaluate our approach through a simulated testbed by using NS3 and Docker, and illustrate the efficiency of our mechanisms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
