A Self-Adaptive Model-Based Wi-Fi Indoor Localization Method

This paper presents a novel method for indoor localization, developed with the main aim of making it useful for real-world deployments. Many indoor localization methods exist, yet they have several disadvantages in real-world deployments-some are static, which is not suitable for long-term usage; some require costly human recalibration procedures; and others require special hardware such as Wi-...

Wi-Fi Based Positioning System

 Abstract—In today’s era position of any outdoor element can be determine precisely using GPS. But in the indoor environment like house, colleges, underground construction site GPS does not work well. As now-a-days all house and colleges are equipped with Wi-Fi access point, precise position can be found out using Wi-Fi using method name Received Signal Strength Indicator (RSSI). A series of e...

Designing High Performance Enterprise Wi-Fi Networks

Use of mobile computing devices such as laptops, PDAs, and Wi-Fi enabled phones is increasing in the workplace. As the usage of corporate 802.11 wireless networks (WLANs) grows, network performance is becoming a significant concern. We have built DenseAP, a novel system for improving the performance of enterprise WLANs using a dense deployment of access points (APs). In sharp contrast with wire...

Ambient Interference Effects in Wi-Fi Networks

This paper presents a measurement study of interference from six common devices that use the same 2.4 GHz ISM band as the IEEE 802.11 protocol. Using both controlled experiments and production environment measurements, we quantify the impact of these devices on the performance of 802.11 Wi-Fi networks. In our controlled experiments, we characterize the interference properties of these devices, ...
