The security of such network is a major concern. To improve the security of such network, technique proposed here is securing routing protocol AODV through the use of Symmetric Encryption algorithm AES. This secures the data as well as preserves the confidentiality. Further future work to be carried as of node authentication using IP address and using the AODV routing protocol and digital signature scheme. Keywords-- Mobile ad-hoc, symmetric encryption algorithm, confidentiality, AODV, Digital signature, IP address The nodes involved in a MANET should collaborate amongst themselves and each node acts as a relay as needed, to implement functions e.g. security and routing. C] Multihop Routing: Basic types of ad hoc routing algorithms can be singlehop and multihop, based on different link layer attributes and routing protocols. Single-hop MANET is simpler than multihop in terms of structure and implementation, with the cost of lesser functionality and applicability. When delivering data packets from...
