Round-robin access for G/G/1 queue modelling machine-type communication gateways in long-time evolution networks

A round-robin transmission model is proposed for machine-type communication gateways (MTCGs) served by long-time evolution e-NodeBs (eNBs). The function of the MTCGs is to collect and buffer data from their subscribed MTC devices (MTCDs) until they are served by an eNB. The service of each MTCG follows an independent and identically distributed G/G/1 queue model, which can be employed with any distribution according to the MTCD traffic characteristics. The system performance is analysed based on queuing theory.
