A LAN network is considered as a scenario in which the nodes regularly have the need to transmit, which generates a constant dispute to access the medium, and BPL (Broadband Power Line) networks are no exception. BPL technology is characterized by using the electrical network as a means of transmission and for this it makes use of several standards, IEEE 1901 among them, due to its wide acceptance. Based on the growth in the demand for new services and to offer acceptable levels of QoS (Quality of Service), IEEE 1901 operates a hybrid medium access mechanism, supported by CSMA/CA and TDMA. However, this strategy has shown little efficiency when increasing the number of nodes in the network, be cause only one of the nodes can transmit at a time. This article proposes a medium access mechanism on OFDMA (Orthogonal Frequency-Division Multiple Access), based on weighted voting game theory and supported by the Deegan-Packel power index, in order to optimize access. in the time and frequency domain, improving network performance and allowing multiple nodes to transmit simultaneously.
