Abstract: | In this paper, we analyze the problem of context adaptation in delay and disruption tolerant networks (DTNs). Initially, we performed experiments with well-known routing protocols to evaluate how much distinct configurations impact their performance. The results show that the performance is highly configuration dependent and improper configuration can lead to a performance up to 506.6 % worse than the best configuration tested. This motivates us to propose CARTOON (context-aware routing protocol for opportunistic networks), a novel routing protocol for DTNs based on the concept of context-adaptation. We evaluate CARTOON through simulations and the results show that our propose outperformed other well-known protocols, exhibiting results that are, on average, at 95 % of the computed optimum delivery rate. |
