We believe that existing wire solutions such as HomePNA2.0 and HomePlug and wireless solution such as HomeRF are the most promising solutions, because of its cost-effectiveness. However, MAC protocols of these solutions provide only Class of Service (CoS) using priority mechanism like HomePNA and HomePlug or consider only voice among real-time traffics like HomeRF. For these reasons, we perceive the needs of the new MAC protocol which is no new wire solution and provides guaranteed Quality of Service (QoS) for not only voice but also video and audio. In light of this, we present the design and software implementation of a new MAC protocol for the Home Network called the HomeMAC. Our evaluation results of software implementation verify that HomeMAC can provide low delay and low jitter to the real-time traffic by reservation of the bandwidth.
