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 SOctopus
and some other secure Ad-hoc routing models is
presented in this paper.
