Power line communication is an excellent candidate for home network. The rapid growth of AV application in home network brings with itself a new and more stringent set of QoS requirements. MAC protocol is a critical issue for efficient network resources utilization and QoS guarantee. Harsh medium environment and unstable PHY layer transmission make PLC MAC layer implementation very difficult. In this paper, we first illustrate the topology and QoS requirements of PLC home network, then analyze and compare the feasibility and QoS performance of different kind of MAC protocols in PLC home network. Recent achievements of PLC MAC layer protocol study and their QoS mechanisms are also digested. In the conclusion, it is pointed out that contention/contention-free hybrid MAC layer protocol is most suitable for PLC home network.
