Full-duplex (FD) wireless communication is evolving into a practical technique, and many studies are being conducting in this area, especially regarding the physical layer. However, to exploit FD benefit successfully, efficient medium access control (MAC) protocols are crucial as well as physical layer advances. Numerous FD-MAC protocols have been proposed, but these MAC protocols cannot address all the issues encountered in this area. In addition, many half-duplex (HD) capable devices are present in existing wireless local area networks (WLANs), so there is an urgent need to integrate FD clients and HD clients in the same WLAN. We refer to this type of WLAN as a heterogeneous WLAN (Het-WLAN). In this paper, we propose an FD-MAC for Het-WLAN, which considers all possible types of FD transmissions. Our proposed FD-MAC protocol suppresses inter-user interference. Simulation results demonstrated that a significant throughput gain (about 96%) could be achieved by using our proposed FD-MAC compared with traditional HD communications. Moreover, our proposed MAC obtained better performance (average throughput gain of about 11%) compared with another existing FD-MAC design. In addition, probability analysis suggested that the total probability of FD transmissions increased rapidly as the WLAN approached saturation conditions.

“…With half-duplex transmission, the relay node receives the data from the source node at the first half frame and forwards it to the destination node (BS) at the second half frame. With the full-duplex transmission, the relay node receives the signal from the source node and forwards the data to the destination node (BS) during the entire frame [23]. Figs.…”

Abstract-To enable multiple mobile users to transmit their signals simultaneously over the same sub-channels, the virtual multiple-input multiple-output (V-MIMO) techniques can exploit the multiple-input multiple-output (MIMO) spectrum efficiency gain. Traditional V-MIMO transmission schemes mainly focus on maximizing the throughput of grouped mobile users without taking into account the quality-of-service (QoS) provisionings. In this paper, we propose the optimal power allocation schemes with statistical QoS provisionings to maximize the effective capacity of non-collaborative/collaborative V-MIMO wireless networks, respectively. For non-collaborative V-MIMO wireless networks, the mobile users in one V-MIMO group transmit signals independently over the same sub-channels. In the view point of existing mobile users, they solely occupy the sub-channels. Thus, the existing mobile users employ the QoS-driven single-user power allocation scheme to maximize their effective capacity. By converting the non-collaborative V-MIMO transmission optimization problem into a strictly convex optimization problem, we derive the QoS-driven power allocation scheme for the newly added mobile users to maximize their effective capacity. For collaborative V-MIMO wireless networks where the mobile users in one group can collaboratively transmit their signals, we derive the QoS-driven collaborative power allocation schemes for both the existing and the newly added mobile users. Also conducted is a set of simulation evaluations, showing that our proposed power allocation schemes for V-MIMO wireless networks outperform the other existing schemes.

In this paper, a transmit-sense-receive mode-based simultaneous transmit-andreceive cognitive antijamming (SCAJ) strategy is proposed to enhance spectrally efficient of airborne networks in congested electromagnetic spectrum environment.We explore the performance of spectrum sensing based on energy detection in SCAJ system. The tight close form expressions of jamming detection and false-alarm probability are derived under different channels, the throughput of individual SCAJ system is analyzed, and SCAJ transceiver-based airborne ad hoc network capacity is presented for air platform equipping with digital beamforming antennas. Simulation results show that proposed SCAJ technology can improve the antijamming capability and airborne ad hoc network capacity compared to the half-duplex cognitive antijamming scheme. It is an effective approach to solve the problem of designing airborne networks arise from the limited availability of spectrum and the desire to provide much higher data rates. without central coordination among the radios. However, it still has no opportunity to exploit the spectrum hole to transmit signal, so as to prevent EM interference from the internal and external RF equipment. Recently, cognitive radio (CR)-based antijamming (CAJ) communication technology was put forward. It can implement high efficient information transmission using available spectrum holes by spectrum sensing; therefore, the ATN performance can be greatly improved in a congested EM spectrum scenario.Cognitive radio has arisen commercially over the last decade, enabling dynamic spectrum access (DSA) scheme to share open spectrum. 1 The goal of DSA is to relieve the lack of EM spectrum, which is the scarcest resource to implement wireless communication. Most involved the study of CR has considered that secondary (unlicensed) users (SU) use the spectrum holes of primary (licensed) users (PU) without interfering primary communication and developed DSA mechanism to opportunistically access the licensed frequency channel. Consequently, spectrum sharing between PU and SU has been achieved, and spectral efficiency of wireless network is to be maximized.In this paper, the use of CR for antijamming wireless communication operating in ATN is conceived, where malicious jammers exist in addition to scarce EM spectrum. Because of the limitation of the congested EM spectrum resource among tactical radios, it is challenging to extend cognitive antijamming to airborne ad hoc networks operating in environments where electronic attacks and little infrastructure exist. Therefore, it is imperative that future tactical radios can dynamically to use the spectrum resources efficiently.Some researchers have carried on the beneficial exploration CAJ-based military communication technology. In literature, 2-4 Li analyze theoretically the jamming capacity of cognitive jammer and the antijamming performance of cognitive wireless network. A high frequency radio prototype system based on dynamic spectrum antijamming is reported in Zhu et al. 5 The competing ...
