Abstract:
Wireless sensor networks (WSN) is a new technology, foreseen to be used increasingly in the near future, and security is an important issue for it. However because of nodes resource limitations, other schemes proposed for securing general ad hoc networks, are not appropriate for WSNs. Usually some nodes act maliciously and they are able to do different kinds of DoS attacks. In order to make the network more secure, malicious nodes should be isolated from the network. In this thesis, we model the interaction of nodes in WSN and intrusion detection system (IDS) as a Bayesian game formulation and use this idea to make a secure routing protocol. By this approach nodes are motivated to act normally and gain reputation, and IDS can perform better by using the history of the game. As this game approaches to Nash equilibrium, it leads to a defense strategy for the network
