An ad-hoc network is a multi-hop wireless network where all nodes cooperatively maintain network connectivity without a centralized infrastructure. If these nodes change their positions dynamically, it is called a Mobile Ad-hoc NETwork (MANET). Since the network topology changes frequently, efficient adaptive routing protocols such as AODV, DSR are used. As the network is wireless, security becomes the major issue in Mobile Ad hoc Networks. Some of the attacks such as modification, fabrication, impersonation and denial of service attacks are due to misbehavior of malicious nodes, which disrupts the transmission. In this paper, the authors proposed an efficient secure AODV routing protocol. Simulation results show that their proposed routing algorithm provides a better level of security and performance than existing works.
