摘要
Delay tolerant networks (DTNs) aims to augment the effects of unscheduled delivery opportunities to increase the message delivery ratio and shorten delivery time in distributed and unstructured networks. When end-to-end routing paths cannot persistently exist in dynamic environments, message delivery depends on relay nodes that repeatedly forward message copies to encountered nodes during movement. In this talk, the speaker would like to introduce his team’s recent advances on new message delivery schemes by exploiting the natural phenomenon of node aggregation in practical application domains. Performance results under different mobility benchmarks manifest positive effects of density-aware message delivery schemes, compared with Epidemic, Spray and Wait, and PRoPHET.
