Quality-of-Service (QoS) in wireless environments. When performing a
handover, request and allocation of resources have to be performed in the
shortest possible time to avoid disruptions for the user service.
Therefore, it is preferable to ensure resource availability in
advance, which we call anticipated handover.
This article provides an overview of a
comprehensive QoS architecture supporting such handovers.
The presented architecture and protocol were implemented
and evaluated by measurements. They show that anticipated handovers
not only outperform hard handovers regarding handover latency, but
that they also provide functional and robustness advantages.
