Abstract
In this paper, we propose a real-time service based on retransmission slot in low rate WPAN. In the proposed scheme, during the communication period of the beacon-enabled mode in LR-WPAN standard, a special GTSs is dynamically assigned for retransmission of the packet that fails during a real-time service such as voice. This provides a time diversity in the severe channel error environments to support the required QoS. Analytical results show that this scheme achieves a much higher throughput and better transmission success rate per GTS slot than conventional schemes such as a common reserved scheme in LR WPAN.
