Analysis on Buffer-Aided Energy Harvesting Device-to-Device Communications.

We address the performance analysis issue of the buffer-aided energy harvesting device-to-device communication system. A Coupled Processor Queuing Model with data packet and energy packet poisson arrival but interactive departure is proposed. The Quasi-Birth and Death method is adopted to obtain the steady state transition probability of proposed queuing model. Then the expressions of throughput, delay and packet drop rate for both data queue and energy queue are derived. The simulations verify the accuracy of the theoretical derivation results.
