Abstract

In fifth generation and beyond Internet of things (5G-IoT), the buffer-aided relaying network provide an efficient way to maintain the coverage area and enhance the edge user's transmission experience. However, the effect of non-ideal factor to the buffer-aided relaying network, such as the signaling overhead, have not been investigated. In this paper, we propose a practical hybrid bit-level network coding (BNC) for the buffer-aided relaying network while taking the unreliable transmission, limited relay-buffer size and signaling overhead into consideration. Afterward, we derive its concise closed-form expressions and the associated upper bound expressions for the throughput, queuing delay and overflow probability. Monte-Carlo simulation proves the validness of our analysis. Simulation results also demonstrate that compared to existing studies, our proposal can enhance the system energy efficiency (EE) performance, and buffer size has a positive effect on the EE performance.
