An Efficient Networking Approach for Broadband PLC Networks

Broadband PLC (power line communication) has become one of the most important communication technologies for Smart Gird applications, especially for AMI (Advanced Metering Infrastructure) and HAN (Home Area Network). Currently, most broadband PLC products are based on OFDM, DMT or Spread-Spectrum technologies. Their performances differ from each other on certain circumstances. Before the STA device successfully entered the network, because the STA device was receiving After the beacon frame of any network, the network access request will be sent after the CCO receives the network access request sent by the STA device, if the MAC address of the STA device is not in the whitelist, it sends a downlink message to reject the STA device's network access. If there are multiple CCO, it will cause waste of useless uplink and downlink packets, prolong networking time, and cause channel congestion. To solve the problems, An Efficient Networking Approach for broadband PLC Networks is proposed. The present invention propose a new broadband PLC networking, it's characteristic is after any neighbor network receives a beacon of ,it selects the network with the closest MAC address of the device to the network. Results of OPNET simulation show that compared with the scheme of literature [10] mechanism and purposed new mechanism ANENA-BPLC. Purposed new mechanism ANENA-BPLC has improved Network Success rate, Average End to End delay, the network CCO and STA Id's, Number of packets
