An Efficient MAC Protocol for PLC Based on STA Slots

Abstract

Nowadays PLC are existence measured as a substitute for high hustle data infrastructures and internet interaction. Presently BPLC is a part for AMI and HAN with several channels in nearly each rooms, PL’S are now the most collective network in the ordinary or small office. This works presents a new media access control MAC protocol for access PLC networks. The beacon time slot allocates all access points to their own site time slots. It is not necessary to send each STA's beacon slot in a beacon period, reducing the time for sending data messages. In the process of multi-site access to the network, some STAs still broadcast and send discovery beacons when no new nodes are connected to the network, which will cause the broadcast of the discovery beacon to be worthless and waste broadcast frames and discovery beacon slots. In order to send as many data frames as possible in a beacon period. Outcomes of OPNET 14.5 simulation illustration that compared with the system of literature [12] protocol and IEEE 1901.1 protocol. Proposed new EMA-PLCS protocol has enhanced Success rate, Average ETE delay of network, Network throughput, and number of STA slots.
