Power-Saving in Wi-Fi Hotspots: An Analytical Study

Wi-Fi hotspots are one of the most promising scenarios for mobile computing. In this scenario, a very limiting factor is the scarcity of mobile-device energetic resources. Both hardware and software architectures of current devices are very inefficient from this standpoint, mainly the networking subsystem. This work analyzes a power-saving network architecture for the mobileInternet access thro...

A New Approach to Model Wi-Fi Signal Strength

Fingerprinting is a widely used technique for indoor positioning, especially for Wi-Fi positioning systems. It is essential to create the fingerprint database in training phase. A quick survey can save labour effort and time; however it normally means the sacrifice of the positioning accuracy since a small number of measurement the signal strength can’t represent the real signal distribution we...

Geometric and Signal Strength Dilution of Precision (DoP)Wi-Fi

The democratization of wireless networks combined to the emergence of mobile devices increasingly autonomous and efficient lead to new services. Positioning services become overcrowded. Accuracy is the main quality criteria in positioning. But to better appreciate this one a coefficient is needed. In this paper we present Geometric and Signal Strength Dilution of Precision (DOP) for positioning...

The Wi-Fi Roaming Game

We propose an extensive-form game as a model for pricing roaming charges in 802.11 wireless data networks. We specify utility functions for the three agents involved in the game: the wireless user and the visited and home operators. With realistic assumptions, we use the model to find optimal roaming prices for delay insensitive users.
