  Mobile Ad hoc Networks (MANETS) are transient networks of mobile nodes,
connected through wireless links, without any fixed infrastructure or central
management. Due to the self-configuring nature of these networks, the topology
is highly dynamic. This makes the Ad Hoc Routing Protocols in MANETS highly
vulnerable to serious security issues. In this paper, we survey the common
security threats and attacks and summarize the solutions suggested in the
survey to mitigate these security vulnerabilities.
