Wireless networking is an emerging technology that will allow users to access information and services regardless of their geographic position. In contrast to infrastructure based networks, all nodes are mobile and can be connected dynamically in an arbitrary manner. Ad hoc networks proved their efficiency being used in different fields but they are highly vulnerable to security attacks and dealing with this is one of the main challenges of these networks today. Recently, some solutions are proposed to provide authentication, confidentiality, availability, secure routing and intrusion detection in ad hoc networks.
