“…The performance benefit of full-duplex is then expressed in terms of throughput per unit area. This paper supports the existing work in this area [2][3][4]6,8,9,[12][13][14]16] seeking to identify the performance gain that full-duplex nodes offer communications networks in the MAC layer. Our approach is to present a simple network setup to which we apply a simplified network interference model, like [12] with characteristics evolved from the classic Gupta and Kumar model [5], and apply a reduced complexity MAC protocol.…”

“…We further this analysis using a simulation approach, however limiting our study entirely to the MAC layer. Comparing simulations, using HD-MAC based on analysis in [1] and FD-MAC based on those proposed in [8,14,16], we are able to quantify the resulting performance increase for our simple network setup when fullduplex nodes are introduced, focusing our study around the 'bottleneck problem' and 'hidden node problem' introduced above. We consider a three node network where two of those nodes are client devices that can communicate directly with the third node, a wireless access point, via a single hop, see fig 1.…”

(0) 117 954 5201 A.Doufexi@Bristol.ac.uk ABSTRACT This paper demonstrates the potential performance gains that the introduction of full-duplex nodes can provide to a wireless network. The paper focuses on two common issues in current communications networks; bottlenecks and hidden nodes. The technical approach used simulates a simplified MAC protocol and scans over the parameter space for which full MAC simulations would not be computationally tractable. In contrast to most literature which focusses on saturated traffic, this study identifies the capacity region, i.e., vectors of demand that can be met by the system. The study shows that introducing full-duplex access points alone mitigates against the problem of bottlenecks, reduces the impact of hidden nodes and can increase the capacity of a network. When full-duplex access points are able to work with full-duplex clients, the capacity gain is much more significant, however it is shown that much of this capacity gain occurs at uneven demand combinations. When the demand to all nodes is equally high, the introduction of full-duplex capability to clients is shown to increase the number of transmission attempts resulting in a significantly increased number of collisions and reduced network performance. Further we observe that at low traffic levels, a full-duplex access point may improve throughput by simply transmitting a busy tone to silence other transmissions whilst it receives, mitigating against the hidden node problem.

“…The performance of both of these modes in meeting the performance metrics of a wireless system is limited by some inevitable constraints as highlighted in the following [83]. The performance of the FDD mode is constrained by the inflexible bandwidth allocation, quantization for the Channel State Information at the Transmitter (CSIT) and the guard bands between uplink and downlink.…”

Full-Duplex (FD) wireless technology enables a radio to transmit and receive on the same frequency band at the same time, and it is considered to be one of the candidate technologies for the fifth generation (5G) of wireless communications due to its advantages including potential doubling of the capacity, reduced end-to-end and feedback delays, improved network secrecy and efficiency, and starting with a detailed overview of FD-enabled DSS, we provide a comprehensive survey of recent advances in this domain. We then highlight several potential techniques for enabling FD operation in DSS wireless systems. Subsequently, we propose a novel communication framework to enable CST in DSS systems by employing a power control-based SI mitigation scheme and carry out the throughput performance analysis of this proposed framework. Finally, we discuss some open research issues and future directions with the objective of stimulating future research efforts in the emerging FD-enabled DSS wireless systems.

“…Some proposals aim at exploiting FD operation to allow nodes to transmit concurrently as primary or secondary transmitters and receivers and allow relaying nodes to receive transmissions while forwarding their own [11], [18], [19]. Other proposals [2], [24] focus on the interplay between the up-link and down-link with an access point of a wireless LAN or base stations in 5G wireless networks. The fact that SIC enables a node to implement collision detection has not been fully exploited, and the interplay between collision-avoidance and collision-detection techniques in ad-hoc networks has not been addressed in the past.…”

Abstract-Carrier-Sense Multiple Access with Collision Avoidance and Detection (CSMA/CAD) is introduced and analyzed. The new protocol operates in a single channel and consists of taking advantage of self-interference cancellation to enable collision detection (CD) in the context of collision-avoidance (CA) handshakes in multi-hop wireless networks. It is shown that CSMA/CAD eliminates the collisions of data packets in the presence of hidden terminals. The throughput of CSMA/CAD is analyzed and compared with the throughput of CSMA, CSMA/CA, and dual busy-tone multiple access (DBTMA). The analysis results show that CSMA/CAD provides better performance than the other channel-access schemes aimed at combating hidden terminals, and that the throughput degradation due to hidden terminals in CSMA/CAD is limited compared to CSMA.
