Evaluation of models Hybrid (MH) and Smart (MS) based on game theory for resources allocation in HomeplugAV networks

摘要

The communications standard by powerline HomePlug AV does not have an appropriate resource optimization mechanism for a multiuser environment, which significantly affects the network performance when the number of users increases. In light of the foregoing, it is proposed the use of the Smart Model (SM) that uses the cooperative game theory, and especially the bankruptcy problem and the Shapley value, as a strategy to optimize the allocation of bandwidth on each node, according with the demand in the service, the number of stations and PLC channel conditions. The article presents a scenario under saturated traffic conditions to validate whether the proposed model (SM-HPAV) operates better than the model that uses HomePlug AV (HM-HPAV). The evaluation process presented favorable results for SM-HPAV which shows that the use of the cooperative game theory, supported on the Shapley value can be regarded as an excellent alternative when performing optimization processes bandwidth in a channel PLC and with the possibility to be implemented in low-cost embedded systems because it does not require complex operations for estimation, significantly improving levels of throughput, delay and efficiency of PLC technology.
