abstract

mobile ad-hoc networks have attracted a great deal of attentions over the past few years. considering their applications, the security issue has a great significance in them. security scheme utilization that includes prevention and detection has the worth of consideration. in this paper, a method is presented that includes a multi-level security scheme to identify intrusion by sensors and authenticates using biosensors. optimizing authentication and intrusion detection combination, we formulate the problem as a partially observable distributed stochastic system. in order to reduce the computation time, the parallel forward algorithm of hidden markov model has been used. due to the possibility of misdetection of the sensor and in order to increase the accuracy of observations, more than one sensor is selected in every step, the observations obtained from the sensors are combined for more accurate identification, and the system decides about the security status based on combined observations of the sensors. bayesian theory has been used in sensors evidence fusion brought by increased accuracy and network security, which will be observed in the simulations. the use of this theory causes the increase of accuracy and security on networks.

Ontology for MANET Intrusion Detection

At present, the security issues on MANET have become one of the primary concerns. The MANET is more vulnerable to attacks as compared to wired networks due to distributed nature and lacks of infrastructure. Those vulnerabilities are nature of the MANET structure that cannot be removed easily. As a result, attacks with malicious intent have been and will be devised to exploit those vulnerabiliti...
