Abstract
Provided is a distributed and asynchronous implicit token carrier sense multiple access/collision avoidance (CSMA/CA) protocol guaranteeing quality of service for both real time and non-real time traffic. The implicit token CSMA/CA protocol allocates a band in an entire bandwidth to voice traffic and allows the remaining bands to be used for data traffic. The implicit token CSMA/CA protocol includes applying a token passing protocol to transmit voice traffic in real time by having a band in an entire bandwidth allocated using a predetermined data frame and applying a CSMA/CA mechanism to transmit data traffic in non-real time by employing remaining bands not allocated to the voice traffic using another predetermined data frame.
