Abstract
This paper introduces a novel MAC algorithm for IR-UWB radio networks named CA-MAC. The algorithm configures the error protection level and the average pulse period per link in order to control the shared medium utilization in an IR-UWB network. This strategy deviates from recent research efforts towards access schemes based on IEEE 802.15.4 MAC and exploits research results of game theory and cognitive radio. Results obtained by simulation show that CA-MAC outperforms ALOHA in scenarios with high system loads in terms of pulses per second.
