A Scalable Secure Routing Protocol for MANETs

Wireless mobile ad-hoc networks (MANETs) are becoming highly applicable in many fields. Due to MANETs special characteristics, secure routing may be one of the most difficult areas to deal with as opponents can add themselves to a MANET using the existing common routing protocols. This paper proposes a new model of routing protocol called ARANz, which is an extension of the original authenticated routing for ad-hoc networks (ARAN). Later, we will demonstrate that apart from the authentication methods adopted from ARAN, ARANz aims to increase security, achieve robustness and solve the single point of failure and attack problems by introducing multiple local certificate authority servers. We will reveal that via dealing with the network as zones and using restricted directional flooding, our new model will exhibit better scalability and performance.
