The Relationship

In this paper, we study the performance of a technique called time reversal for cooperative communication in a mobile wireless environment. To put the work in context, a brief introduction to time-reversal communication (TRC) in general and cooperative TRC in particular is presented. Performance of a proposed cooperative TRC scheme is evaluated numerically via a simulated indoor environment containing multiple wireless communication nodes. We characterize the behavior of the peak power received at a target node as a function of the number of cooperating transmitting nodes and as a function of the distance of the target from its predicted location within the simulated environment. The results demonstrate that the performance of cooperative TRC is less sensitive to uncertainty in the target position than might be expected from standard assumptions regarding the relationship between signal wavelength and spatial channel correlation in a complex multipath environment.

Mobile wireless computing is changing the way in which people work, allowing work to occur in a broad range of environments on tasks that previously required fixed location-based, networked computing environments. Along with this greater work flexibility, it is also likely that these mobile work environments contain various types of distractions that could potentially affect the task performance of knowledge workers. Drawing on distraction-conflict theory, this research proposes a model of knowledge worker task performance within the context of a mobile wireless work environment. To test this model, a controlled laboratory experiment was conducted that contrasted task complexity and distraction levels on the task performance of individuals within a mobile wireless environment. Results indicate that regardless of task complexity, productivity losses will occur under both lower and higher levels of distraction. The implications of these results for future research and for the deployment of mobile technologies within organizations are discussed.
