Efficient Resource Allocation Model For D2D Communication Under Overlapping Area of Multiple Cellular Cell

摘要

Device-to-Device (D2D) communications was originally projected in cellular networks as an innovative prototype for improving network performance. The rise of new applications such as location aware content distribution introduced new user scenarios for D2D communications in cellular networks. The preliminary studies exhibited that D2D communications has advantages such as reduced communication delay and increased spectral efficiency. However, D2D communication approach introduces problems in terms of interference control overhead and conventions that are still open research problems. Therefore, efficient interference modelling design are required. The existing model has focused on addressing interference considering D2D association operating on same cell and very limited work is carried out in addressing interference issues of D2D user operating on overlapping area of multiple cell. For overcoming research challenges, this work presented Efficient Resource Allocation (ERA) model for D2D under cellular network as a game theory model. Experiment are conducted to evaluate performance of ERA. The outcome shows ERA attained significant performance improvement over state-of-art models in terms of sum rate (utility), successful packet transmission, and revenue.
