Abstract

In this paper, we propose a method to avoid distributed reservation protocol (DRP) conflicts in WiMedia MAC. A WiMedia device with our method immediately compares its own medium access slots (MASs) to neighbor's requests. If there is a reservation conflict, the device's reservation is modified and a beacon frame based on the modified reservation is transmitted to remove the 65ms delay that occurs when a reservation conflict arises. The simulation result using VBR video traffic indicates that our method reduces reservation conflicts by about 12%. The proposed method is adapted to implement the WiMedia MAC-PHY modem chip.
