An Expatiate Game-Theory Based Analysis OnMultiattacker Scenario in MANETS

摘要

Nodes in Mobile Ad Hoc Network (MANET) have mobility which causes the network vulnerable to attacks. Malicious nodes can attack MANET for utility and other gains as they have ability to move. Regular node sin the network has certain strategies towards their functionality and security. In the same fashion, malicious nodes must be having their own strategies to make attacks on the network. It is important to analyze the profiles of both kinds of nodes. Recently Li et al. proposed a framework that analyzes interactions among the nodes in Mobile Ad Hoc Network in order to secure the network from malicious access. Their solution is based on game theory. Regular nodes update their security aspects based on the malicious nodes and their behavior. In the same manner the malicious nodes also think about the risk of being caught. They also think about when to flee to avoid the risk. In this paper we practically implement the proposed game theory. We built a prototype application to simulate the MANET scenario that analyzes interactions among the nodes. The empirical results revealed that the proposed framework is useful.
