Abstract

Ultra wideband (UWB) technology has emerged as a solution for the wireless interface between medical sensors and a personal server in future telemedicine systems. The WiMedia Alliance has specified a distributed medium access control protocol based on UWB for high-rate wireless personal area networks. The legacy WiMedia standard must statically reserve an additional transmission time of 30 %, since transmission time is limited to network environment in wireless network. When channel environment is deteriorating badly, the additional reservation may not have enough time. Because the legacy WiMedia standard must wait the next reservation period if sending device does not transmit data frames in the current reservation period, the transmission delay occurs. Also, in a good channel environment, the additional reservation time results in a waste of performance. Therefore, there is a need to provide the reliability of data transmission as sending device predicts channel environment in WiMedia network and reserves the distributed reservation protocol (DRP) reservation duration considering the estimated channel environment. In this paper, we propose a novel resource reservation scheme considering channel environment in WiMedia network. The simulation results show that proposed protocol can enhance the throughput and delay performance and improve energy efficiency by minimizing the idle period of DRP reservation block.
