Disaster management systems (DMSs) aim to mitigate the potential damage from disasters by ensuring immediate and suitable assistance to victims. Disaster management is a challenging problem because while information needs to be processed in real time, the damaged environment can prevent it from being disseminated to processing centres. Our goal is to exploit available technologies such as Wireless Sensor Network (WSNs) and Vehicular Ad hoc NETworks (VANETs) to forward alerts from victims to rescue services. We propose an opportunistic data dissemination protocol (3DMAT) for disaster management in which both WSNs and VANETs participate in decision-making for the dissemination process so that messages are delivered in a timely manner. The simulation results show that the proposed protocol performs data dissemination more efficiently than other protocols. 3DMAT calculates the quality of nodes and the link between them to select the most relevant relay. Our protocol is 47% faster and generates a 17% lower communication load and 14% fewer redundant messages. These improvements are due to a selection strategy that targets the most relevant nodes to relay information.

灾害管理系统（DMS）旨在通过确保为受害者提供及时和适当的援助来减轻灾害的潜在危害。灾难管理是一个具有挑战性的问题，因为尽管信息需要实时处理，但受损的环境可能阻止信息传播到处理中心。我们的目标是利用无线传感器网络（WSN）和车载Ad hoc NETworks（VANET）等可用技术将受害者的警报转发到救援服务。我们提出了一种用于灾难管理的机会数据传播协议（3DMAT），其中WSN和VANET都参与了传播过程的决策制定，以便及时传递消息。仿真结果表明，所提出的协议比其他协议更有效地进行数据分发。3DMAT计算节点的质量以及它们之间的链接以选择最相关的中继。我们的协议速度提高了47％，通信负载降低了17％，冗余消息减少了14％。这些改进归因于针对最相关节点以中继信息的选择策略。
