摘要：An ad hoc network is a collection of wireless nodes communicating among themselves over possibly multi-hop paths, without the help of any infrastructure. The nature of ad hoc networks is dynamically changing and they have a fully decentralized topology. Hence, security is hard to achieve due to the dynamic nature of the relationships between the participating nodes as well as the vulnerabilities and limitations of the wireless transmissions medium AODV is based on distance vector routing, but the updates are shared not on a periodic basis but on an as per requirement basis. The control packets contain a hop count and sequence number field that identifies the freshness of routing updates. In our work we look at AODV in detail, study and analyses various attacks that can be possible on it. Then we look into some existing mechanism for securing AODV protocol.
