Mobile Ad Hoc Networks Security: Challenges and solutions

Security has become a primary concern in order to provide protected communication between mobile nodes in a hostile environment. Unlike the wire line networks, the unique characteristics of mobile ad hoc networks pose a number of nontrivial challenges to security design, such as open peer-to-peer network architecture, shared wireless medium, stringent resource constraints, and highly dynamic network topology. In this article only focus on the fundamental security problem of protecting the multi hop network connectivity between mobile nodes in a MANET.
