Security Aware Routing Protocol for Mobile Ad Hoc Networks

Secured communication in mobile ad hoc network is a crucial issue due to dynamic nature of the network topology. Due to lack of centralized control, issuing certificates from a centralized certification agent is not possible in ad hoc network. The major problem in providing security services in such infrastructure-less networks is how to manage the cryptographic keys that are needed. In MANET any node may compromise the packet routing functionality by disrupting the route discovery process. These unique characteristics of mobile ad hoc networks such as open network architecture, shared wireless medium, stringent resource constraints and highly dynamic topology cause a number of nontrivial challenges to security design. These challenges make a cause for building multi-fence security solution that achieves both extensive protection and desirable network performance. In particular, the absence of a central authorization facility in an open and distributed communication environment is a major challenge, espec...
