Abstract

The realm of wireless ad hoc networks is a relatively new one, even with advancement in wireless networks in general. Essentially, these are networks that do not have an underlying fixed infrastructure. Mobile hosts "join" in, on the fly, and create a network on their own. With the network topology changing dynamically and the lack of a centralized network management functionality, these networks tend to be vulnerable to a number of attacks. If such networks are to succeed in the commercial world, the security aspect naturally assumes paramount importance. There is a need to devise security solutions to prevent attacks that jeopardize the secure network operation. This survey chapter aims to provide a state-of-the-art view of security in wireless ad hoc networks. An attempt has been made to discuss the core issues and requirements of security, followed by the current state of research and development in this area, which includes algorithms, architectures, and network management schemes.
