Background/Objectives: HPAV uses Time Division Multiple Access (TDMA) for the voice and video package transmission, in order to offer properQoS levels. The main goal of this paper is to propose a model that allows assessing the performance of a Power Line Communication network (PLC) under TDMA, during the transmission of multimedia packages, using a AFR package (Aggregation with Fragment Retransmission). Methods/Statistic Analysis: In this paper, the throughput saturation concept for a finite Number of stations. For that reason, it will be assumed that the package size is fixed of bits to a rate of Mbps. In order to analyze the performance of the network supported in TDMA, a model is proposed; such model is based on a Round Robin Scheduler (RR) scheme, according to the MAC structure hybrid for HPAV. Subject Relevance: AFR is a scheme that was proposed to reach a high efficiency rate in the layer of Media Access Control (MAC) and that, to date, has only been considered in Wireless networks supported in 802.11n. Additionally, up to date, no models to assess the performance over TDMA applied to HPVA in different bibliographic sources have been found. Results: Based on the obtained results, it was possible to observe that the model permits to assess the probability of loss packages, the efficiency MAC over TDMA, the throughput and the levels of delay on a PLC network during a transmission of video and voice under a AFR scheme, according to the number of stations, the size of the containment window and the available bandwidth in the channel. Application/Improvements: The model proposed can be considered as a tool in future research papers, for the transmission of Voice and video over HPVA, to assess aspects related to QoS.
