Rate Adaptation Scheme for Slot Reservation in WiMedia MAC
Junwhan Kim, Jaedoo Huh · 2007
The rate adaptation technique is an effective way to reliably transmit data in wireless networks. In this paper, we propose a novel rate adaptation scheme using not only range measurement operation (RMO) for measuring distance, but also average receive signal strength indication (RSSI) values for recognizing further obstacles. A decided data rate based on an estimated channel condition is used for both reliable data transmission and slot reservation in distributed reservation protocol (DRP) of WiMedia MAC. Last, we show the throughput measurement of our scheme working on WiMedia MAC.
