Context adaptation in delay and disruption tolerant networks

Delay and disruption tolerant network scenarios present contrasting traits that may cause significant variation in the performance of routing protocols. In this work, the evaluation of protocols RAPID, MaxProp, PRoPHET and Spray and Wait on three different scenarios with contrasting characteristics enabled the analysis of the impact of these fluctuations in performance and the verification that parameterizable protocols are able to boost substantially the performance. In addition, we add to PRoPHET the ability to adapt to the scenarios characteristics (context), depending on the network density and message load. Simulations with real traces of mobile devices have proven its effectiveness, increasing performance by up to 19.96% compared to the standard configuration.
