Connections characteristics analysis in delay tolerant mobile networks

In delay tolerant mobile networks with spars nodes, transferring messages from sources to destinations are accomplished by nodes custody transfer for reliability for the rarity of end-to-end links. Different nodes movement models are adopted in traditional networks, but they are hard to meet the necessity of large-time scale disruption and long-range transmissions. So the hotspots model was designed and proposed to increase the probability of transfer and fasten the speed of bundles spreading. The number of connections and cumulative distribution function of new connections are analyzed with different simulation parameters. We found that the new connections of hotspot model in delay tolerant mobile networks are more important than older ones in successfully delivering bundles.
