OLSR-based Topology Discovery for Mobile Situational Awareness Systems

In this paper, we propose a non-intrusive approach for connectivity visualization of OLSR-based MANET topology based on local topology databases available in an OLSR node. Two different scenarios are considered: a central (full view) topology from a command and control location, or a nodal (partial) view from an ad-hoc node. A simulation based analysis is conducted to calculate total number of active links at a particular time in full and nodal topology views. Also the error rate of network topology discovery based on total undiscovered link both mobile and static scenario is considered and reported in this paper.
