HomePlug AV (HPAV) is the standard for distribution of Audio/Video content as well as data within the home by using the power line. It uses a hybrid access mechanism that combines TDMA with CSMA/CA for MAC technology. The CSMA/CA protocol in HPAV has two main control knobs that can be used for access control: contention window (CW) size and deferral counter(More)
—The data rates of wireless networks are getting faster and faster. With this trend, IEEE 802.11a, published in 1999 to provide faster data transmission rates, is one of the strongly considered next generation wireless LAN standards. It uses CSMA/CA as the medium access control protocol and OFDM as the physical layer technology. In this paper, to enhance(More)
Random access mechanisms play an important role in wireless networks and have been extensively studied in recent years. Although many previous studies have proposed enhanced algorithms, they only considered either throughput or fairness. In this paper, we propose an efficient random access mechanism called Multi-round Collision Avoidance (MrCA). The key(More)
