An Experimental TVWS Spectrum Allocating Testbed for IEEE 802.11af Networks using PAWS
Yu-Lin Hsieh, Wen‐Kang Jia · 2014
Since the use of wireless devices in the already overcrowded ISM bands had been further growing recently. Realization of wireless communications in TV white space is one of the most urgent research and development issues to accommodate rapidly increasing wireless access. In order to ensure avoidance of interference from secondary users to primary users, adoption of White Space Database (WSDB) is one of the important strategies. In this paper, we introduce the concept of IETF Protocol to Access White Space Database (PAWS), and use it to connect a WSDB and dynamic allocating spectrum resources and monitoring the use of those resources in the IEEE 802.11af (White-Fi) networks. We have implemented the PAWS API and WSDB for spectrum allocation and show that mechanism operations with an experimental IEEE 802af network, which enables White-Fi Access Point (AP) to share the TVWS in a fine geolocation and timescale.
