Collision avoidance and resolution multiple access with transmission groups

摘要: The CARMA-NTG protocol is presented and analyzed. dynamically divides the channel into cycles of variable length; each cycle consists a contention period group-transmission period. During period, station with one or more packets to send competes for right be added group stations allowed transmit data without collisions; this done using collision resolution splitting algorithm based on request-to-send/clear-to-send (RTS/CTS) message exchange non-persistent carrier sensing. ensures that transmission if requests in previous variable-length train packets, which are transmitted by have been successfully completing an RTS/CTS periods. As long as maintains its position group, it able collision, An upper bound derived average costs obtaining first success algorithm. This then applied computation utilization fully connected network large number stations. These results indicate powerful mechanism combination floor acquisition allocation multiple access.
