Betweenness estimation in OLSR-based multi-hop networks for distributed filtering

作者:

Highlights:

• Traditional firewalling on multi-hop networks has a critical impact on network resources.

• Centrality metrics can be used to identify a core of nodes able to enforce filtering/monitoring.

• OLSR routing information can be used to efficiently identify this core of nodes without overhead.

• We propose a method that scales on realistic network dimension and topologies.

• Enforcing firewalling only on this core reduces the impact and stops most unwanted traffic.
