- W4200475891 abstract "With the rapid development of wireless sensor networks, people are increasingly demanding various of indoor Location-based Services (LBSs). In this circumstance, for the sake of proliferating the use of existing indoor Wi-Fi network for target localization, it is much necessary to investigate the impact of mobile Access Points (APs) like mobile phones operating as Wi-Fi mobile hotspots on indoor Wi-Fi localization error bound. To achieve this goal, we first analogize the process of indoor Wi-Fi fingerprint-based localization into the process of information transmission in a basic communication model. Second, the interference caused by mobile APs and environment noise is recognized as the channel noise in information transmission. Third, considering the time-variant property of Wi-Fi fingerprints in the actual indoor environment, we simulate the information transmission channel as colored Gaussian noise channel, and then calculate the error bound of indoor Wi-Fi localization from the capacity of this simulated channel. Finally, we come to the conclusion that mobile APs have non-ignorable impact on indoor Wi-Fi localization error bound." @default.
