Delay Tolerant Mobility Aware Routing/Mobility Dissemination Protocol for the Airborne Network

| Abstract |

|
Despite "airborne network (AN) topology design"
and careful planning of AN trajectories, unexpected
disruptions (from hardware failures to changes in mission
requirements and hostile attacks) may cause nodes not to
connect to one another directly or indirectly either because
they are out of one another’s range or because nodes do not
meet one another according to their preplanned trajectories.
Since an end-to-end path within the AN is not always
guaranteed, packets have to be delivered in a delay-tolerant
fashion, namely, some intermediate nodes will need to
buffer packets during times of disconnectivity. In our earlier
work we developed Mobility Aware Routing Protocol
and Mobility Dissemination Protocol (MARP/MDP) that
used preplanned trajectories of airborne nodes to make
intelligent routing decisions preemptively. In this paper we
present a delay-tolerant strategy (MARP/MDP+DTN) to
predict the minimum end-to-end delay and obtain the corresponding
path. In addition, MARP/MDP+DTN accounts
for local queueing (MARP/MDP+DTN+QC) to minimize
congestion and further improves end-to-end delay with the
positive side effect of load-balancing. Simulation results
have shown an improvement of 52% in packet delivery
ratio in MARP/MDP+DTN. MARP/MDP+DTN+QC also
exhibits extremely short latency, about 90% reduction
from MARP/MDP+DTN in highly congested network.
Moreover, MARP+DTN+QC balances local traffic 67%
better than MARP+DTN in high traffic load scenarios.
