灾难发生时获救的幸存者人数取决于搜救队的效率。因此，必须尽可能发展沟通、协调和协作。目前的通信基础设施，无线电设备，只允许我们传输音频信号，所以通过提供互补的通信媒体和服务来增强组交互是一个挑战。由在具有有限无线覆盖的对等架构中操作的可穿戴设备形成的ad-hoc网络似乎适合于这种需求。我们设计了一个特设的分布式共享内存系统，专注于对等移动性产生的问题，提供一个透明的方式进行交互的应用程序。此外，我们开发了一个模拟模型来分析获得可靠介质所需的复制量。在为应用程序提供的透明度和系统的可用性之间出现了一种折衷。结果表明，建立一个可靠的通信系统是可能的。
The number of victims rescued alive when a disaster occurs depends on the efficiency of search and rescue teams. Hence, communication, coordination and collaboration must be developed as best as possible. Currently the communication infrastructure, radio gear, permits us only to transfer audio signals, so enhancing group interaction by providing complementary communication media and services is a challenge. An ad-hoc network formed by wearable devices operating in a peer to peer architecture with limited wireless coverage seems appropriate for this need. We have designed an ad-hoc distributed shared memory system, focused on issues generated by peer mobility, to provide a transparent way for applications to interact. Also, we developed a simulation model to analyze the amount of replication needed to obtain a reliable medium. A trade-off appeared between the transparency provided to the applications and the system's availability. The results suggest that it is possible to build a reliable communication system.
