A Variable Slot Length TDMA Protocol for Personal Communication Systems

We present a new TDMA-based scheme intended for carrying traffic withdiverse QoS requirements in mobile environments, e.g.,Personal Communication Systems (PCS).In contrast to mostother TDMA protocols for mobile applications, instead oftrying to fit the offered traffic to the slot size, our solution adaptsthe slot size to the offered traffic.This feature is combined with a dynamic and responsive bandwidth scheduler.As demonstrated by our performance studies, the proposedscheme is more flexible and incurs lower bandwidth overhead than otherTDMA-based solutions.
