Background and Objective: Mobile ad hoc network (MANET) is an emerging and developing
area of wireless networks. These networks are formed by nodes that are within the transmission
coverage area of each other. MANETs are otherwise quoted as anytime, anywhere network.
Methods: The nodes that are involved in forming the network themselves act as routers to route information
among them, thus forming self-configuring community of nodes. As other wired and wireless
networks, the various layers of MANETs are also prone to various forms of attacks.
Conclusion: In this paper, we focus on network layer attacks in MANETs and the measure to overcome
the severity caused by those attacks by implementing elliptic curve cryptography (ECC).
