Abstract (EN): In this paper, we propose a real-time publish-subscribe communication scheme for IEEE 802.11e networks, named Group Sequential Communication (GSC). The GSC intends to improve the HCCA mechanism by adopting a simple approach based on the Virtual Token Passing (VTP) protocol which uses a real-time group concept, where the real-time members of the group are granted a high-priority and sequential access to the communication medium. Their main achievements are the reduction of the Polling, individual ACKs and NULL frames overheads between the controller and the polled stations. In order to improve the reliability of the GSC scheme was developed a fault-tolerant mechanism based on a block acknowledge strategy to avoid missing real-time message deadlines.
