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.]]></p></abstract>

La tecnología BPL se caracteriza usar las redes energéticas como medios de transmisión y para esto usa varios están dares, estando el IEEE 1901 entre ellos, debido a su amplia aceptación, Basados en el crecimiento de la demanda de estos nuevos servicios y para ofrecer niveles aceptables de QoS (Calidad del Servicio en sus siglas en inglés), el IEEE 1901 opera un mecanismo híbrido de acceso al medio soportado por CSMA/CA y TDMA. Sin embargo, esta estrategia ha mostrado muy poca eficiencia al incrementarse el número de nodos en la red, ya que solo puede haber un nodo transmitiendo al mismo tiempo. Este artículo propone un mecanismo de acceso al medio en OFDMA (Orthogonal Frequency-Division Multiple Access), basado en juegos de votación ponderada y soportado por el índice de poder Deegan-Packel con el fin de optimizar el acceso en el tiempo y frecuencia del dominio, mejorando así el desempeño de la red y permitiendo que múltiples nodos transmitan simultáneamente.]]></p></abstract>
