A Scalable Secure Routing Protocol for Managed-Open Mobile Ad-Hoc Networks

Abstract

Mobile Ad-hoc networks are getting progressively more popular. In such networks, nodes are continuously moving, hence, seeking an efficient route from a particular source to projected destination is a vital issue. Moreover, choosing a secure route is a tough area to deal with since adversaries may include themselves within these routes unless a strict secure procedure is implemented along with routing protocols. In managed-open environment, such as that formed by peers at a conference, using already established infrastructure as a starting point for assuring security is likely. Thus, this research proposes a novel paradigm of routing protocol named S-Octopus. Through tackling with area as sectors and utilizing restricted directional flooding, S-Octopus tries to achieve improved scalability. Moreover, S-Octopus seeks to increase robustness and alleviate single point of failure and compromise problem via picking up numerous sector certificate authorities. A qualitative comparison among S-Octopus and some other secure Ad-hoc routing models is presented in this paper.
