MANETs have unique characteristics like dynamic topology, wireless radio medium, limited resources and lack of centralized administration, as a result, they are vulnerable to different types of attacks in different layers of protocol stack. Each node in a MANET is capable of acting as a router. Routing is one of the aspects having various security concerns. In this paper, we will present survey of...
Due to wireless communication, dynamic topology, limited resources and lack of centralized administration, MANETs are vulnerable to various types of DoS attacks on network layer. In Gray hole and Black hole attacks malicious nodes deliberately disrupt data transmission in the network by sending incorrect routing information. It is a challenge to keep the communication route free from such attackers...
