Ad hoc network routing and security: A review

Ad hoc network is a collection of wireless mobile nodes dynamically forming a local area network without the use of any existing network infrastructure or centralized administration. One problem in the design of such network is its wireless vulnerabilities and limited physical security. This paper considers the security attributes and goals of ad hoc network, reviews the latest developments of current routing and security mechanissm including encryption, protocols, user authentication, and physical security. It also explores the new approaches trying to solve current problems and points out the future research directions. These methods will be helpful in the military and other security-sensitive fields.
