Abstract :
A centralized dynamic priority based burst level per-VC cell scheduling scheme is proposed for transmission of multiservice traffic over TDMA/TDD channels in a wireless ATM network. In the proposed scheduling scheme the number of slots allocated to a VC (virtual circuit) is changed dynamically depending on the traffic type, traffic load, TOE (time of expiry) value of the data burst and data burst length. The performance of the proposed scheme is evaluated through computer simulation for realistic voice, video and data traffic models and their QoS requirements. Simulation results show that, the proposed scheme can provide reasonably high channel utilization with QoS guarantee in a multiservice traffic environment. Such a scheme is easy to implement and can result in an energy efficient TDMA/TDD MAC (medium access control) protocol for broadband wireless access. In addition, it can be easily adapted as a MAC scheme in the emerging DS (differentiated services) enhanced wireless IP networks
