This research proposal is mainly driven by two developments in wireless mesh networks. Firstly, new technologies for wireless communications allow data rates up to several GBit per second. For the efficient usage of these high data rates, frame aggregation at MAC layer is inevitable and leads to new research questions. Secondly, a rapid trend away from pure FTP-like traffic, towards video streaming is recognizable in mobile communication scenarios.Therefore, the goal of this research proposal is to quantitatively evaluate future wireless mesh networks with frame aggregation for multi-hop communication. To that end analytical/numerical stochastic models are developed for selected issues and validated with the results of extensive measurement studies in an indoor multi-hop mesh testbed, thus ensuring realistic results. Furthermore, the analysis of the configurable stochastic models allows generalizing the findings and further a sensitivity analysis of parameters towards interferences.

该研究提案主要由无线网状网络的两项发展推动。首先，无线通信新技术允许数据速率高达每秒几GB。为了有效利用这些高数据速率，MAC 层的帧聚合是不可避免的，并引发了新的研究问题。其次，在移动通信场景中，从纯粹的类似 FTP 的流量转向视频流的快速趋势是显而易见的。因此，本研究提案的目标是定量评估未来具有用于多跳通信的帧聚合的无线网状网络。为此，针对选定的问题开发了分析/数值随机模型，并通过室内多跳网格测试台中的广泛测量研究的结果进行了验证，从而确保了真实的结果。此外，可配置随机模型的分析允许概括研究结果并进一步进行参数对干扰的敏感性分析。
