Security Strategy in Ad Hoc Networks

Security has become a primary concern in telecommunication protection between mobile nodes in a hostile environment.The characteristics of mobile ad hoc networks,such as open peer-to-peer network architecture,shared wireless resource and highly dynamic network topology,pose a number of challengers to the security design.In this paper we focus on the fundamental security problem of protecting the multihop network connectivity between mobile nodes in a MANET.We reach the conclusion that the complete security solution should span both layers,and encompass all three security components of prevention,detection,and reaction.
