Abstract
The use of powerline networks in the access networks is the promising solution to the communication industries. In the powerline networks, the stations share a communication medium, which may cause communication conflicts which results to poor network utilization if there is no efficient Media Access Control Protocol. In this work, the applicability of different Media Access Control protocols including ALOHA, slotted ALOHA, Carrier Sence Multiple Access, Carrier Sence Multiple Access with Collision Detection and Carrier Sence Multiple Access with Collision Avoidance to the Broadband Powerline networks are investigated and suggesting the appropriate techniques. Wireshark Network Protocol Analyzer was used in this work to analyze the data traffic collected from the similar network to that of Kariakoo network which used as the case study, and the data simulated using Matlab. From the simulation results, the pure ALOHA protocol gives the maximum throughput of 15.99%, slotted-ALOHA protocol gives 21.16% and CSMA/CA gives the maximum throughput of 30.6% under the same traffic load of 0.28Erlang keeping arrival rates and packet lengths unchanged. But further reduction of the network size into two collision domains the MAC throughput of CSMA/CA increases to 58.11% which is better performance compared to all other investigated MAC protocols. From the results CSMA/CA was suggested to be the appropriate MAC protocol in the given network.
