Abstract
Critical MANET environments such as military battlefields and disaster recovery operations impose a number of requirements such as the need for robustness and performance within high mobility scenarios; also, they impose some constraints such as Hostile attacks, RF range and cost, battery limitations.We studied the core-based routing protocol PUMA, in addition to two ant-based routing protocols MANHSI and AAMRP to identify their drawbacks while working in critical MANETs. Finally, we propose a novel routing protocol named Adaptive Secure Headship Following Induction Keeping (ASHFIK) to work ideally in critical MANETs scenarios.In this paper, we discuss the structure of ASHFIK, which uses a new mechanism called the Headship Mechanism, which provides always a standby core to work if the original core is down. After studying performance analysis of ASHFIK compared to PUMA, we can conclude that ASHFIK is particular suitable for most critical MANETs scenarios.
