“…Nowadays, a large number of CSMA/CA protocol optimization schemes have been proposed. In [16], a model based on Discrete-Time Markov Chain (DTMC) was proposed to analyze the network performance of IEEE 802.11 Distributed Coordination Function (DCF) and In-Band Full-Duplex (IBFD). This model had a small analysis error.…”

The CSMA/CA algorithm uses the binary backoff mechanism to solve the multi-user channel access problem, but this mechanism is vulnerable to jamming attacks. Existing research uses channel-hopping to avoid jamming, but this method fails when the channel is limited or hard to hop. To address this problem, we first propose a Markov decision process (MDP) model with contention window (CW) as the state, throughput as the reward value, and backoff action as the control variable. Based on this, we design an intelligent CSMA/CA protocol based on distributed reinforcement learning. Specifically, each node adopts distributed learning decision-making, which needs to query and update information from a central status collection equipment (SCE). It improves its anti-jamming ability by learning from different environments and adapting to them. Simulation results show that the proposed algorithm is significantly better than CSMA/CA and SETL algorithms in both jamming and non-jamming environments. And it has little performance difference with the increase in the number of nodes, effectively improving the anti-jamming performance. When the communication node is 10, the normalized throughputs of the proposed algorithm in non-jamming, intermittent jamming, and random jamming are increased by 28.45%, 21.20%, and 17.07%, respectively, and the collision rates are decreased by 83.93%, 95.71%, and 81.58% respectively.

“…Thus, these IUP solutions are only effective in very limited scenarios where a node sends two or three data frames and receives only one data frame in response from the server. In [18], a frame aggregation method is used to reduce an IUP. However, the frame aggregation method can be used in limited scenarios, such as real-time communications, where a node has many uplink data frames.…”

Recently, full-duplex radio has attracted attention as a solution for wireless local area networks (WLANs) where traffic is exploding but available frequency bands are insufficient. Full-duplex radio exploits various self-interference cancellation technologies to transmit and receive signals concurrently in the same frequency band. Thus, the efficiency of the frequency band is doubled compared with that of conventional half-duplex radios. However, to effectively exploit full-duplex radio, new problems that do not exist in conventional half-duplex radio, such as fullduplex link setup, inter-node interference avoidance, and idle uplink period (IUP), must be addressed. We propose a full-duplex medium access control (MAC) protocol to effectively exploit fullduplex radio by addressing these problems. In particular, our MAC protocol uses an IUP to transmit an acknowledgment (ACK) frame and report the buffer information of nodes. Accordingly, an access point can gather the node's buffer information during the IUP and schedule the transmission of nodes without competition. In addition, because the uplink ACK frame is transmitted during the IUP, additional channel usage time for the uplink ACK frame transmission is not required. Therefore, the proposed MAC protocol improves the WLAN throughput by reducing the number of control frame transmissions and the IUP. The results of our performance analysis and simulation show that the MAC protocol achieves throughput improvements compared with those of previous studies.

Full-duplex (FD) communication has been attractive as the breakthrough technology for improving attainable spectral efficiency since the 5G mobile communication system. Previous research focused on self-interference cancellation and medium access control (MAC) protocol to realize the FD system in wireless networks. This paper proposes an optimal achievable transmission capacity (OATC) scheme for capacity optimization in the FD multihop wireless networks. In this paper, the proposed OATC scheme considers the temporal reuse for spectral efficiency and the spatial reuse with transmit power control scheme for interference mitigation and capacity optimization. OATC scheme controls the transmit power to mitigate interference and optimizes the transmission capacity, which leads to the optimal achievable network capacity. We conduct the performance evaluation through numerical simulations and compare it with the existing FD MAC protocols. The numerical simulations reveal that considering only the concurrent transmissions in the FD system does not guarantee optimal transmission capacity. Moreover, the hybrid mechanism, including the sequential transmissions, is also crucial because of the interference problem. Besides, numerical simulation validates that the proposed OATC scheme accomplishes the optimal achievable network capacity with lower interference power and higher achievable throughput than the existing MAC protocols.
