Towards Optimised Retransmission Reservation in Real-Time Wireless TDMA

Free registration required

Executive Summary

Providing real-time guarantees in wireless networks requires the reservation of transmission time not only for transmissions but also for retransmissions. Retransmissions are required to ensure that real-time reliability targets are achieved due to the unreliable nature of the wireless medium. Simplistic approaches such as immediate retransmission over a number of times are wasteful in terms of available transmission time and bandwidth. This paper proposes a resource allocation and retransmission mechanism that takes into account the independence of transmissions to different destinations and the characteristics of the occurrence of burst errors.
