Asymmetric Key Cryptography based Ad-hoc on Demand Distance Vector Protocol (ACAODV)

Abstract

Disaster is sudden, catastrophic events which origins are natural calamities and man-made, cause greater loss, damage and destruction of life and property. Since there are several geographical areas in the globe in which natural calamities such as flood, earthquake, hurricanes, landslides, cyclones, volcanic eruptions, tsunamis, storms etc. and man-made disaster likes rescue operation, terrorist and Naxalite attacks are more common. Hence it is too expensive to establish infrastructure based cellular network because it may not provide solution to the users in the areas in which such types of calamities mostly happens. Mobile ad-hoc network (MANET) is one of the best solution in affected areas as discussed above because it is infrastructure less network and setup anywhere and anytime. MANET have some issues like lack of centralize monitoring, open standards, narrow bandwidth, mobility, storage, and variation in link hence security is much more required than the wired network. Ad-hoc On-Demand Distance Vector (AODV) routing protocol reduces control packet overhead, adaptability with dynamic changing network, low setup delay, and less memory requirement but suffer from various attacks such as impersonation, byzantine, black whole and resource consumption attack. To address the security vulnerabilities and shortcomings of previous methods, we proposed an asymmetric key cryptography-based scheme for securing the AODV (Ad hoc On-Demand Distance Vector) routing protocol in this paper.
