Cryptography Techniques based on Security of AODV in MANETs - A Survey

Networks popularity and demand has motivated the development of mobile adhoc networks (MANETs). MANETs are a kind of wireless adhoc network which is infrastructure less. Each device or nodes are free to move independently in any random direction due to this links between the devices is not constant. This dynamic nature of network topology makes security issues more complex. In this paper, we discuss the solutions for security threats in AODV protocol. Security threats like wormhole attack, black hole attack, eaves dropping etc can defended by using cryptographic techniques like RSA, DES, AES. Main issues with security mechanisms that are available is their effect on performance of algorithm like more processing power, packet drop, throughput etc. Finally, concluding over the solutions for security through these algorithms so that performance and security can be enhanced in future.
