Security in Ad Hoc Networks

Abstract

In ad hoc networks the communicating nodes do not necessarily rely on a fixed infrastructure, which sets new challenges for the necessary security architecture they apply. In addition, as ad hoc networks are often designed for specific environments and may have to operate with full availability even in difficult conditions, security solutions applied in more traditional networks may not directly be suitable for pro- tecting them. A short literature study over papers on ad hoc networking shows that many of the new generation ad hoc networking proposals are not yet able to address the security problems and they face. Environment-specific implications on the re- quired approaches in implementing security in such dynamically changing networks have not yet fully realized. 1
