Context-aware multicast routing scheme for disruption tolerant networks

: Disruption Tolerant Networks (DTNs) are emerging solutions to networks that experience frequent network partitions and large end-to-end delays. Several schemes have been proposed for multicast routing in DTNs assuming the availability of different amounts of knowledge about network topology, etc. In this paper, we propose a context-aware adaptive multicast routing (CAMR) scheme which can handle different network scenarios better than the existing multicast delivery schemes for DTNs that we are aware of. Our scheme can address the challenges of opportunistic link connectivity in DTNs. Simulation results show that our CAMR scheme performs better than the DTBR and OS-multicast schemes. The CAMR scheme can achieve the highest message delivery ratio (8 times more than what DTBR and OS schemes can achieve), with similar delay performance especially when the nodes are very sparsely connected. We also perform sensitivity analysis on the tunable parameters of our CAMR scheme and evaluate the ...
