Background/Objectives: HPAV uses a new retransmission model of lost packages called Aggregation with Fragment Retransmission (AFR), which utilizes CSMA/CA as a mechanism to accessing the media. The main purpose of this paper is to assess the performance of a network supported in HPAV standard under the scheme AFR. Methods/Statistical Analysis: In this paper, the concept of saturation of throughput will be used for a finite number of stations. For that matter, it is necessary to assume that the size of the package is fixed of bits to a rate of Mbps. Additionally, an adaptation to Bianchi’s model was carried out adjusted to the MAC structure of HPAV, which allows to represent CSMA/CA as a Markov’s chain in discrete time of two dimensions. All this is done in order to represent the back-off procedure under a scheme DCF with saturated stations. Relevance of the Subject: AFR is a scheme that was proposed in order to achieve a high efficiency in the control layer of media access (MAC), based on CSMA/CA, and that, to date, has only been considered in Wireless networks supported in 802.11n. To date, similar works have not yet been found applicable to HPAV in the vast bibliographic sources. Results: Based on the obtained results, it was possible to observe that the model allows to assess the probability of lost packages, the MAC efficiency, the throughput and the delay levels in a PLC network, under a scheme AFR, subject to the number of stations, the size of the containment window and bandwidth available in the channel. Application/ Improvements: It is recommended to carry out similar studies under the use of TDMA over HPAV for the voice and video broadcasting, having into account that HPAV uses a mechanism of accessing to the hybrid media in order to offer adequate levels of QoS.
