Abstract

HomePlug AV (HPAV) es uno de los estándares de mayor aceptación sobre la tecnología PLC, el cual no cuenta con un mecanismo adecuado para la optimización del ancho de banda, realizando procesos de asignación de recursos mediante TDMA (Time Division Multiple Access) y CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) acorde con la clase de servicio. En vista de lo anterior, en el presente artículo se propone el uso de OFDMA (Orthogonal Frequency-Division Multiple Access) como mecanismo de acceso al medio y del valor de Shapley como estrategia para la optimización del ancho de banda en redes que utilizan la red eléctrica como medio físico de transmisión. Acorde con los resultados obtenidos se pudo evidenciar que el uso de OFDMA y el uso de la teoría de juegos cooperativos podría ser considerado como una estrategia adecuada para la asignación de recursos en un canal PLC, ofreciendo adecuados niveles de calidad de servicio.
