In post-disaster scenarios, such as after floods, earthquakes, and in war zones, the cellular communication infrastructure may be destroyed or seriously disrupted. In such emergency scenarios, it becomes very important for first aid responders to communicate with other rescue teams in order to provide feedback to both the central office and the disaster survivors. To address this issue, rapidly deployable systems are required to re-establish connectivity and assist users and first responders in the region of incident. In this work, we describe the design, implementation, and evaluation of a rapidly deployable system for first response applications in post-disaster situations, named RDSP. The proposed system helps early rescue responders and victims by sharing their location information to remotely located servers by utilizing a novel routing scheme. This novel routing scheme consists of the Dynamic ID Assignment (DIA) algorithm and the Minimum Maximum Neighbor (MMN) algorithm. The DIA algorithm is used by relay devices to dynamically select their IDs on the basis of all the available IDs of networks. Whereas, the MMN algorithm is used by the client and relay devices to dynamically select their next neighbor relays for the transmission of messages. The RDSP contains three devices; the client device sends the victim's location information to the server, the relay device relays information between client and server device, the server device receives messages from the client device to alert the rescue team. We deployed and evaluated our system in the outdoor environment of the university campus. The experimental results show that the RDSP system reduces the message delivery delay and improves the message delivery ratio with lower communication overhead.

RDSP：用于灾后管理的可快速部署的无线 Ad Hoc 系统

在灾后场景中，例如洪水、地震和战区之后，蜂窝通信基础设施可能会被破坏或严重中断。在这种紧急情况下，急救人员与其他救援队进行沟通以向中心办公室和灾难幸存者提供反馈变得非常重要。为了解决这个问题，需要快速部署的系统来重新建立连接并协助事件区域的用户和急救人员。在这项工作中，我们描述了一个可快速部署的系统的设计、实施和评估，该系统用于灾后情况下的第一响应应用程序，称为 RDSP。提议的系统通过利用新颖的路由方案将他们的位置信息共享给远程服务器，从而帮助早期救援响应者和受害者。这种新颖的路由方案由动态 ID 分配 (DIA) 算法和最小最大邻居 (MMN) 算法组成。中继设备使用 DIA 算法根据网络的所有可用 ID 动态选择其 ID。而客户端和中继设备使用 MMN 算法来动态选择它们的下一个邻居中继来传输消息。RDSP 包含三个设备；客户端设备将受害者的位置信息发送到服务器，中继设备在客户端和服务器设备之间中继信息，服务器设备接收来自客户端设备的消息以提醒救援队。我们在大学校园的户外环境中部署并评估了我们的系统。实验结果表明，RDSP系统以较低的通信开销减少了消息传递延迟，提高了消息传递率。
