Inter-domain Routing
for Tactical Mobile Ad-hoc Networks
The purpose of this thesis is to provide a
routing solution for a large scale tactical inter-domain network containing
multiple Mobile Ad-hoc Networks (MANETs) and fixed networks. The solution
proposed in this thesis involved using Open Shortest Path First – MANET
Designated Router (OSPF-MDR); which is a modification of OSPFv3 to support MANETs
as well as OSPFv3 in the fixed networks. A border gateway routing protocol
which actualizes wireless mobility features and routing abilities similar to
the Border Gateway Protocol (BGP), named BGP – MANET Routing (BGP-MR),
was also proposed. BGP-MR introduces the dynamic election of gateways and
recursive purging of routes from the BGP table as BGP peers are lost due to
mobility.
The proposed solution is tested to show
OSPF’s ability to provide convergence in large scale networks. Our
results showed that after 20 minutes networks running either OSPF or OSPF-MDR
converged. Also, our results demonstrate BGP-MR’s ability to provide
seamless routing as well as reduced overhead when compared to running BGP in
interconnecting MANETs, regardless of their partitioning and merging
characteristics.
