Mobile Ad hoc NETwork (MANET) is a collection of self-organizing mobile nodes without any
help of centralized administration or established infrastructure. Due to this characteristic,
MANETs are particularly vulnerable to various security threats. In addition, the design of
most MANET routing protocols assumes that there is no malicious node in the network.
Hence, several efforts and researches have been made toward the design of a secure and
robust routing protocol for ad hoc networks. In this paper, we discuss the major attacks that …
