Cooperative aerial wireless networks composed of small unmanned aerial vehicles(UAVs) are easy and fast to deploy and provide on the fly communication facilities in situations where part of the communication infrastructure is destroyed and the survivors need to be rescued on emergency basis. In this article, we worked on such a cooperative aerial UAV-based wireless network to connect the two participating stations. The proposed method provides on the fly communication facilities to connect the two ground stations through a wireless access point (AP) mounted on a UAV using the IEEE 802.11a/b/g/n. We conducted our experiments both indoor and outdoor to investigate the performance of IEEE 802.11 protocol stack including a/b/g/n. We envisioned two different cases: line of sight (LoS) and non-line of sight (NLoS). In LoS, we consider three different scenarios with respect to UAV altitude and performed the experiments at different altitudes to measure the performance and applicability of the proposed system in catastrophic situations and healthcare applications. Similarly, for NLoS, we performed a single set of experiments in an indoor environment. Based on our observations from the experiments, 802.11n at 2.4 GHz outperforms the other IEEE protocols in terms of data rate followed by 802.11n at 5 GHz band. We also concluded that 802.11n is the more suitable protocol that can be practiced in disastrous situations such as rescue operations and healthcare applications.

由小型无人飞行器（UAV）组成的协作空中无线网络易于部署，快速部署，并在部分通信基础设施遭到破坏且需要紧急救助幸存者的情况下提供即时通信设施。在本文中，我们研究了这种基于协作无人机的空中无线网络，以连接两个参与的站点。所提出的方法提供了即时通信设施，以使用IEEE 802.11a / b / g / n通过安装在无人机上的无线接入点（AP）连接两个地面站。我们在室内和室外进行了实验，以研究包括a / b / g / n在内的IEEE 802.11协议栈的性能。我们设想了两种不同的情况：视线（LoS）和非视线（NLoS）。在LoS中 我们考虑了有关无人机高度的三种不同情况，并在不同高度上进行了实验，以测量拟议系统在灾难性情况和医疗保健应用中的性能和适用性。同样，对于NLoS，我们在室内环境中进行了一组实验。根据我们从实验中观察到的结果，在数据速率方面，2.4 GHz的802.11n优于其他IEEE协议，其次是5 GHz频段的802.11n。我们还得出结论，802.11n是更合适的协议，可以在灾难性情况（例如救援行动和医疗保健应用）中实践。
