- Abstract
- IEEE 802.19.1 coexistence system provide two types of coexistence service: information service vs. management service. Information service provides radio environment information that enables 802.11af APs to facilitate channels with its neighbor APs. Each AP determines its operating parameters by itself to mitigate interference using the information. On the other hands, with management service, coexistence manager (CM) determines optimum operating parameters for each AP based on its coexistence decision making. We propose an operating channel selection mechanism for 802.19.1 management service and evaluate performance of interference mitigation among neighbor 802.11af Wireless Local Area Network (WLAN) access points (APs). Using OPNET simulation we compare SNR, BER, and packet drop at 802.11af APs based on BSS coexistence scenario with two services. It is shown that performance of OBSS interference mitigation with management service is superior to that with information service.
