In this paper, we advocate implementing carrier sense multiple access with collision detection (CSMA/CD) in the broadband power line communication (BB-PLC) standard, G.hn, and show the gain in data rate obtained over carrier sense multiple access with collision avoidance (CSMA/CA). The use of CSMA/CD is made feasible due to the recent implementation of in-band full duplex operation in BB-PLC. We provide...
We address the single-source-destination routing problem in a mesh network with a broadcast channel, time-division multiplexing (TDM) and no spatial reuse, which is a special type of the PLC channel. First, the outer bound on the achievable data rate is evaluated. We show that the routing protocols (RPs) with static routing do not allow approaching this data rate limit. Then, we study RP with opportunistic...
This paper carries out a performance evaluation of network coding (NC) for power line communication (PLC) systems based on simulation and theoretical results. NC is deployed at the data link layer (DLL) where it could potentially improve the routing protocol, the MAC scheduler and the ARQ mechanisms. In this paper we focus solely on the combination of NC and ARQ mechanisms. Nevertheless, based on...
A modeling of communication networks is often done in hierarchical way. So, in PLC there are multiple models of channel, physical, datalink and other layers, which are realized separately in multiple programming environments. Nevertheless it is often advantages to do a cross-layer optimization of communication protocols. For this purpose multiple separate models have to be unified in one simulation...
Intensive rollout of smart grids (SG) creates a special demand on communication networks. Especially, they have to supply sufficient quality of service (QoS) to a big number of customers. Therefore the required QoS becomes more demanding (e.g., minimum throughput have to be increased) and in meantime the cost of the network installation and management should be reduced. Power line communication (PLC)...
Usage of Powerline Communication (PLC) technology in-home for entertainment applications and in access networks for management of smart grid (SG) applications has lately received much interest from customers and manufacturers of communication devices. For the further promotion of this technology on the market a PLC performance study is helpful. This has become a hot topic for many researchers. As...
Improvement of communication protocols for energy management purposes has become a challenging part of smart grid systems development. Powerline communications (PLC) has many advantages for being used in this area. Many PLC communication protocols use CSMA/CA channel access schemes on Multiple Access Protocol (MAC) layer. This paper presents an enhancement of the CSMA/CA broadband PLC protocols operation...
This paper investigates the backoff algorithm for Narrowband Power Line Communications (PLC) Medium Access Control (MAC) protocol. Specifically, the paper considered the MAC designed by Yitran and implemented within its Differential Code Shift Keying (DCSK) technology. In this algorithm width of the contention window is calculated based on the estimated number of active nodes in the network. Further...
