“…• we investigate the system performance of FF-NDMA as a function of the CP length (R ), for different SNR and load conditions, and we compare FF-NDMA with S-ALOHA, classical NDMA [18], and H-NDMA 4 [31]. As we will see, the energy consumption is reduced with FF-NDMA as compared to H-NDMA in certain situations due to the lower control signaling to be decoded.…”

“…In this section, we first compare FF-NDMA protocol with classical NDMA [18] and H-NDMA [31], and then present the system model for FF-NDMA. Figure 2 shows the protocol differences between NDMA 5 and FF-NDMA with R = 3.…”

“…H-NDMA requires extra signaling load from the BS towards devices to request additional repetitions on a HARQ basis [31], once the repetitions of NDMA have been completed. On the other hand, in FF-NDMA, control signaling is only needed to receive ACK at those CPs in which a packet was transmitted.…”

“…Stability analysis of NDMA was addressed in [28][29][30]. Finally, the hybrid automatic repeat request (HARQ) concept was applied to NDMA in [31] (named H-NDMA) in order to deal with reception errors at low/medium SNR by forcing devices involved in a collision of P devices to transmit repetitions more than P−1 times. This way, packet reception was significantly improved at low SNR with H-NDMA as compared to classical NDMA.…”

“…In particular, NDMA-based protocols are highly attractive for massive MTC. NDMA has been deeply analyzed in the recent literature with different protocols (e.g., H-NDMA [31]). However, FF-NDMA misses such wide analysis while it is suitable for massive MTC scenarios due to its low associated signaling load and reduced implementation complexity.…”

To support communications of a large number of deployed devices while guaranteeing limited signaling load, low energy consumption, and high reliability, future cellular systems require efficient random access protocols. However, how to address the collision resolution at the receiver is still the main bottleneck of these protocols. The network-assisted diversity multiple access (NDMA) protocol solves the issue and attains the highest potential throughput at the cost of keeping devices active to acquire feedback and repeating transmissions until successful decoding. In contrast, another potential approach is the feedback-free NDMA (FF-NDMA) protocol, in which devices do repeat packets in a pre-defined number of consecutive time slots without waiting for feedback associated with repetitions. Here, we investigate the FF-NDMA protocol from a cellular network perspective in order to elucidate under what circumstances this scheme is more energy efficient than NDMA. We characterize analytically the FF-NDMA protocol along with the multipacket reception model and a finite Markov chain. Analytic expressions for throughput, delay, capture probability, energy, and energy efficiency are derived. Then, clues for system design are established according to the different trade-offs studied. Simulation results show that FF-NDMA is more energy efficient than classical NDMA and HARQ-NDMA at low signal-to-noise ratio (SNR) and at medium SNR when the load increases.

This paper firstly analyzes the transmission mechanism of the wireless broadband multi-media services in the MSW-ARQ(Multi-channel Stop-and-Wait ARQ) system. Considering the real-time multimedia service's four features (high requirement for delay but allows some loss rate, the constraints of the delay and jitter), in order to meet with professional standard, we model the real-time multimedia service packet transmission as an M [X] /G/1 queuing model for MSW-ARQ. The packet transition probability is derived by constructing steady state Markov Chain based on the method of selecting the reference packet. On the basis of equivalent service delay, we also solve the packet mean service delay. Then under the given condition, we analyze the influence of the channel number and channel environments on the mean delay through numerical simulating. The characteristics and superiorities of multi-channel transmission mechanism in wireless communication are checked enough by solving the M [X] /G/1 queuing model. So this paper provides useful thought and approach for optimizing system delay and throughput by checking the change of channel environments and the used number of parallel channels.

Power-line communication (PLC) is a promising communication technology of constructing IoT (internet of things) systems, and it employs IEEE 1901 as its medium access control (MAC) protocol. Current studies about IEEE 1901 MAC performance analysis do not consider the influence of physical layer's retransmission protocols, i.e., ARQ (automatic repeat request) and HARQ-CC (hybrid ARQ with chase combining). Moreover, how 1901 protocol affect the energy consumption in PLC networks, and whether 1901 protocol has bound performance are also unsolved in these existing works. Focusing on the above problems, we put forward a cross-layered theoretical model to insightfully analyze 1901 protocol, where the impacts of physical layer's retransmission protocols (ARQ and HARQ-CC), channel fading modes and practical configurations (buffer size, finite traffic load, etc.) are comprehensively taken into consideration in the modeling process. On this basis, we derive the closed-form expressions of 1901 MAC metrics considering retransmission protocols. Furthermore, we construct an energy consumption model, and provide the bound performance analysis for 1901 protocol. Finally, we evaluate the performance of 1901 protocol under different retransmission protocols and system parameters, and verify the proposed crosslayered theoretical model.
