Abstract :
A novel carrier-sense multiple-access (CSMA) scheme for a UWB ad-hoc network is proposed and evaluated. UWB is a kind of spread spectrum communication and it is possible to detect the distance between the nodes. With this positioning capability of the UWB systems, a DS-CDMA (DS-UWB) scheme with variable spreading factor is used. A novel CSMA scheme that employs the correlation of the spreading code is proposed.
