Abstract

Recently, two trends in wireless communication are observable. First, traffic patterns tend to be unsaturated, due to an enormous increase of traffic types like mobile video and voice streaming. Second, new standards like IEEE 802.11n or IEEE 802.11ac allow huge physical data rates up to several Gbit/s. However, to utilize these data rates an efficient usage of the new frame aggregation feature is necessary. We formulate an analytical model that captures the impact of frame aggregation on routing and transform it into an integer linear program. Furthermore, we propose a heuristic approach that simplifies the computational complexity and show both through extensive simulations and real-world testbed experiments that an aggregation-aware routing scheme helps to efficiently aggregate several unsaturated flows and leads to decreased end-to-end delay and decreased contention in wireless multi-hop networks.

具有帧聚合的无线多跳网络中的聚合感知路由
近年来,无线通信有两种发展趋势。首先,由于移动视频和语音流等流量类型的巨大增长,流量模式往往不饱和。其次,像IEEE 802.11n或IEEE 802.11ac这样的新标准允许高达几Gbit/s的巨大物理数据速率。然而,为了利用这些数据速率,必须有效地使用新的帧聚合特性。我们制定了一个分析模型,捕捉帧聚合对路由的影响,并将其转化为整数线性规划。此外,我们提出了一种简化计算复杂性的启发式方法,并通过广泛的模拟和现实世界的测试平台实验表明,聚合感知路由方案有助于有效地聚合多个不饱和流,从而减少无线多跳网络中的端到端延迟和争用。
