“…In [6], the performance of the network is studied when one priority user is present both in saturated and unsaturated conditions. Then, in [7] an experimental evaluation using a PLC testbed is performed, 1 to 4 high-priority flows contend for the channel in the presence of low-priority flows, CA3 and CA1 access categories are considered. In [8], the access differentiation is evaluated for different frame sizes and numbers of nodes.…”

Abstract-Power Line Communications standards, such asHomeplug and IEEE 1901, aim to provide strict channel access prioritisation in CSMA/CA mode. This is achieved by making lower-priority access categories postpone contention when packets belonging to categories with higher priority are pending for transmission. For this purpose, specific slots in which stations advertise the priority of the current packets to be transmitted are allocated. However, they are only present after the occurrence of successful frame exchanges. Thus, in lightly loaded conditions as well as after channel errors or collisions, the priority resolution mechanism is not employed. In this work, we evaluate the implications of these features on the QoS experienced by each access category. Results show the network provides a complex performance behaviour caused by the interdependence of higherpriority traffic contention and lower-priority traffic preemption.

Abstract-The MAC layer of the IEEE 1901 standard for power line communications employs a CSMA/CA method similar to, but more complex than, this of IEEE 802.11 for wireless communications. The differences between these protocols raise questions such as which one performs better and under what conditions.We study the fairness of the 1901 MAC protocol in single contention domain networks, where all stations hear each other. We examine fairness at the packet level: a MAC layer protocol is fair if all stations share equitably the medium during a fixed time interval. We focus on short-term fairness, that is, over short time intervals. Short-term fairness directly impacts end-user experience, because unfair protocols are susceptible to introduce substantial packet delays. We evaluate short-term fairness with two metrics: Jain's fairness index and the number of inter-transmissions. We present test-bed results of both protocols and compare them with simulations. Both simulation and testbed results indicate that 802.11 is fairer in the short-term when the number of stations N is between 2 and 5. However, simulation results reveal that 1901 is fairer in the short-term for N ≥ 15. Importantly, our test-bed measurements indicate that 1901 unfairness can cause significant additional delay when N = 2. Finally, we confirm these results by showing analytically that 1901 is short-term unfair for N = 2.

Abstract-Power line communication (PLC) technology is at a tipping point and may become ubiquitous as a home networking technology. However, there are concerns regarding RF interference between PLC networks and other radio operators. It is imperative that the interference dynamics of PLC systems be fully understood in advance of any large-scale roll-out. In this work, we experiment with two interference scenarios: notch-infilling due to non-linear mixing and mitigation of radiated emissions using RF chokes. In our controlled test bed environment, we measure RF emissions from the power line devices in the 1 MHz to 30 MHz range. Through the results and simulation, we demonstrate that the effect of non-linear devices may be less of a concern than initially thought, and that simple methods can be employed to control local RF interference.
