Analysis on D2D Heterogeneous Networks with State-Dependent Priority燭raffic

In this work, we consider the performance analysis of state dependent priority traffic and scheduling in device to (D2D) heterogeneous networks. There are two transmission types data wireless communication, such as video or telephone, which always meet requirements high (HP) first. If there is a large amount low (LP) data, will be LP that cannot sent. This situation cause excessive delay packet dropping probability. order solve problem, process queue studied. Considering jump strategy queuing model, with modeled two-dimensional Markov chain. A proposed, can improve discarding data. The quasi birth death method (QBD) fixed point iteration used causality, steady-state probability distribution further obtained.Then, parameters average length, throughput, for both expressed. simulation results verify correctness theoretical derivation. Meanwhile, proposed significantly drop low-priority
