Abstract

The proposed hybrid MAC (H-MAC) protocol characterizes distributed and asynchronous operation. It uses an implicit token for a real-time traffic and the CSMA/CA for a non-real time traffic, guaranteeing QoS. The proposed hybrid MAC protocol allocates the assured bandwidth to real time traffic and dynamically reallocates the remaining bandwidth to a non-real time data traffic.
