A Survey of Context-Aware Mobile Computing Research
Guanling Chen,David Kotz +1 more
TL;DR: This survey of research on context-aware systems and applications looked in depth at the types of context used and models of context information, at systems that support collecting and disseminating context, and at applications that adapt to the changing context.

Experimental evaluation of wireless simulation assumptions
TL;DR: A comprehensive review of six assumptions that are still part of many ad hoc network simulation studies, despite increasing awareness of the need to represent more realistic features, including hills, obstacles, link asymmetries, and unpredictable fading are provided.
Proceedings ArticleDOI
Extracting a Mobility Model from Real User Traces
TL;DR: A method to estimate the physical location of users from a large trace of mobile devices associating with access points in a wireless network is presented and it is discovered that the speed and pause time each follow a log-normal distribution and that the direction of movements closely reflects thedirection of roads and walkways.
Proceedings ArticleDOI
The changing usage of a mature campus-wide wireless network
TL;DR: This paper analyzes an extensive network trace from a mature 802.11 WLAN, including more than 550 access points and 7000 users over seventeen weeks, and defines a new metric for mobility, the "session diameter," to show that embedded devices have different mobility characteristics than laptops, and travel further and roam to more access points.
