| dc.description.abstract | 一般而言，在單頻道無線網狀網路中存在兩種方法可以來最大化網路傳輸容量，分別是在每個傳輸時間隔間裡提高無干擾的傳輸數量，以及增加可行傳輸的傳輸率。然而因為無線通訊干擾的問題，在這兩個方法之間會遇到一些取捨的局面，因此我們要去研究在空間分時多工存取之下的單頻道無線網狀網路中，針對網路傳輸容量所面臨到的空間重用和傳輸功率控制取捨問題。
在這篇論文中，我們提出了一項空間淨空重用的策略來控制淨空區域(無干擾)，以及根據這個策略來決定可同時存取的群組集合，接著我們會針對每一個傳輸單位進行傳輸功率的配置，以最大化整體的網路傳輸容量。根據實驗部分顯示，在我們實驗不同程度之下的空間淨空重用策略所得到不同的網路傳輸容量大小，進而可以了解面臨到的空間重用和傳輸功率控制取捨問題。 | zh_TW |
| dc.description.abstract | In general, there are two approaches to maximize network throughput capacity in a single-channel wireless mesh network: increasing the number of non-interfering transmissions at each time slot by exploiting spatial reuse, and increasing transmission rate of active transmitters. However, a tradeoff of the two ways encounters the wireless communication inference problem. Therefore, we want to investigate the tradeoff between spatial reuse and transmission power control on network throughput capacity in spatial TDMA-based wireless mesh network with single channel. In this paper, we propose a Clean-Air Spatial Reuse Policy to control clean air (interference free) zone and determine the set of concurrent access groups based on the policy. Then, we perform transmission power assignment to each transmitter to maximize the network throughput capacity. Experiment results of the network throughput capacity performance under different levels of the Clean-Air Spatial Reuse policy are presented. | en |
