Multimodal security enforcement framework for wireless ad hoc networks

Securing wireless ad hoc networks in an untrustworthy open environment is always a challenging problem. Lack of central auditing on security and weak incentive for cooperation among nodes in an open network scenario demand a distributed security management scheme preventing selfish and malicious behaviors. In this paper, we present a security enforcement framework for wireless ad hoc networks. This framework is built upon a hybrid and integrated architecture of trust management and intrusion detection, merging the merits of both to guarantee correct services and guard against security attacks.
