In the generalized loss of communication as a result of extensive damage to the communication infrastructure in disaster or emergency scenarios, mobile ad-hoc networks can play an important role in improving communication in the affected areas and working around network disruptions. Communication protocols face a highly dynamic and congested network topology that require highly adaptable solutions. This article proposes a context-aware self-adaptive routing protocol for Delay Tolerant Networks that is able to adapt to different scenarios, allowing the participants of the network to automatically select a DTN protocol according to past performance of routing protocols under the current scenario. We define metrics to implement this approach in a disaster scenario and evaluate our proposal with simulation over three different mobility models. The proposed protocol shows a significant reduction of energy consumption with a good tradeoff with the delivery rate.

在灾难或紧急情况下通信基础设施遭到广泛破坏而导致普遍通信中断的情况下，移动自组织网络可以在改善受灾地区的通信和解决网络中断方面发挥重要作用。通信协议面临着高度动态和拥挤的网络拓扑，需要高度适应性的解决方案。本文提出了一种用于时延容忍网络的上下文感知的自适应路由协议，该协议能够适应不同的情况，允许网络参与者根据当前情况下路由协议的过往性能自动选择DTN协议。我们定义了在灾难情况下实施此方法的指标，并通过对三种不同的移动性模型的仿真来评估我们的建议。
