Mobile ad hoc networks (MANET) is a type of networks that consists of autonomous nodes connecting directly without a top-down network architecture or central controller. Absence of base stations in MANET force the nodes to rely on their adjacent nodes in transmitting messages. The dynamic nature of MANET makes the relationship between nodes untrusted due to mobility of nodes. A malicious node may...
Mobile Adhoc Networks (MANET) are infra structure-less network made up of many mobile nodes and these nodes communicate through a wireless and infrastructure less medium. Security becomes a major challenge for MANET due to its dynamic characteristics, changing topologies and random mobility. This makes MANET susceptible to a wide verity of attacks. Also, a majority of routing protocols in MANETS are...
In this work, we investigate the optimal key generation problem for a threshold security scheme in mobile ad hoc networks. The nodes in these networks are assumed to have limited power and critical security states. We model this problem using a closed discrete-time queuing system with L queues (one per node) randomly connected to K servers (where K nodes need to be contacted to construct a key). In...
Doing research on mobile ad hoc network (MANET) security involves several constraints, some of which are wireless environment's attributes, such as bandwidth and delay, and the correctness of network topology. Testing and evaluating using real wireless devices are costly and somehow impractical, so many tools have been developed in order to create media by which researchers can deeply investigate...
Security is extremely important for the deployment of a mobile ad-hoc networks (MANET) due to its openness to attackers, the absence of an infrastructure, and the lack of centralized administration. Most research efforts have been focused on secure routing protocols, the distributed certificate authority, and key distribution, while a few projects have focused on secure autoconfiguration. However,...
Mitigating misbehavior in mobile ad hoc networks (MANET) requires effective intrusion response systems. In this work, we present an intrusion response scheme that is tailored to support the infrastructure less nature of MANETs. We propose a geographic solution towards excluding misbehaving nodes which is robust against address spoofing from the attacker. In particular, we investigate how an adaptive...
Mobile ad hoc network (MANET) technology spreads widely in these days. It is suitable for environments that need on fly setup. A lot of challenges come with implementing these networks. The most sensitive challenge that MANET faces is the security issue. Traditional public key cryptography (PKC) and identity based cryptography (IBE) are slow and not suitable for these environments because of the nodes...
Mobile Ad Hoc Networks are one of the core enabling technologies for tactical environments such as those envisioned in future military operations and disaster relief scenarios. While a significant amount of research has focused on technology interoperability and protocol design, there has been less work addressing the security and information assurance requirements for such environments. Properly...
