“…This section verifies the theoretical model and compares Multi-CQ performance with different protocols and with different parameters as tested with a C++ simulator. This simulator was also adopted in [9], [21], [22], [23]. Figure 11 shows a comparison of throughputs among Multi-CQ, DCF basic mode [16], DCF RTS/CTS mode [16], CSMA/CA-SIC [6], and CSMA/CQ [9] approximately 15%.…”

In traditional CSMA/CA-based MAC designs supporting successive interference cancellation (SIC), channel utilization is inefficient, because the inherited CSMA/CA-style contention approach often forces the whole channel to remain idle and the early released channel is not utilized. In this paper, we propose Multi-CQ, which is the first software-defined networking (SDN)-based MAC design for wireless LANs that supports SIC and significantly improves the channel utilization. Multi-CQ, adopting SDN's functional separation idea and OFDMA, makes contention and data transmission be executed over two subchannels independently and concurrently, where the superposition coding are used for decoding combined signals, and multiple CQs (contention queues) are introduced to coordinate the concurrency. This concurrent execution greatly reduces the waste in channel contention. Next, adopting SDN's central control idea, Multi-CQ controller selects nodes who can finish their frame transmissions in almost equal time, thereby improving the channel utilization. Finally, we develop a theoretical model to optimize bandwidth allocation for channel contention and data transmission. Extensive simulations verify the effectiveness of our design and the accuracy of our theoretical model. This study is also helpful to better design wireless MAC protocols supporting other advanced functionalities such as MU-MIMO.

“…Background and Related Works Dynamic frequency scaling has been introduced into the wireless mac layer design in paper [17], and investigated further in paper [15]. Dynamic frequency scaling itself has reached technological maturity that can be readily implemented in the chip design for wireless devices [18,19]. In paper [17], workload predictive Ethernet device design has been proposed in that the optimisation scheme based on queueing analysis proves to outperform legacy ones by experiments.…”

To solve the problem of power supply limitation of machines working in wireless industry automation, we evaluated the workload aware service rate control design implanted in the medium access control component of these small devices and proposed a bio-intelligence based algorithm to optimise the design regarding the delay constraint while minimizing power consumption. To achieve this, we provide an accurate analysis of the delay cost of this design and for the first time pinpoint an exact departure process model in order to evaluate the overall delay cost in consideration of the medium access time.
