无线网状网络（WMN）是一种流行的网络架构，用于支持灾难恢复操作。然而，很少有研究工作已经解决了这样的网络的容量问题。这是由于假设灾难场景中的通信网络被构建为支持具有低速率要求的服务，如延迟容忍消息。与此同时，近年来，由于救援行动的数字化和新服务（如VoIP、无人机和机器人）的使用，对更高数据速率的需求有所增加。因此，无线网状网的容量成为未来无线网状网设计的核心问题。本文提出了一种基于第一层分簇的网络来解决WMN的吞吐量瓶颈。所提出的架构进行评估，通过几个真实的世界的测量。所得结果与理论进行了比较。所提出的解决方案示出了吞吐量的改善相比，单无线电WMN和多无线电WMN使用的CoMTaC信道分配策略。
The Wireless mesh network (WMN) is a popular network architecture used to support disaster recovery operations. However, few research works have addressed the capacity problem of such a network. This is due to the assumption that the communication network in disaster scenario is built to support services with a low rate requirement like delay tolerant messages. At the same time, the demand for higher data rates has increased in recent years due to the digitalisation of rescue operations and the use of new services (e.g. VoIP, drones and robots). Therefore, the capacity of the WMN is becoming a central issue in the design of future WMNs. This paper proposes a Layer 1 cluster-based network to solve the throughput bottleneck in the WMN. The proposed architecture is evaluated by several real world measurements. The obtained results are compared with the theory. The proposed solution shows a throughput improvement compared to a single-radio WMN and a multi-radio WMN using the CoMTaC channel allocation strategy.
