“…The time consumed until an antenna detects a pulse/tone signal is at most 5 s [11,12]. Usually, these signals are commonly employed and coupled with some other schemes to point a particular network condition [9]. Moreover, it is assumed that an antenna can detect the received signal strength and the angle of arrival of an incoming signal with a reasonable accuracy.…”

“…Due to its criticality, channel reservation has been target of a number of works in the literature. In [9], the authors proposed a novel technique to reduce network latency during channel reservation where the nodes are employed with half-duplex, directional antennas. The proposed scheme, termed DPTCR, relies on pulse/tone signals to reduce network latency while performing channel reservation.…”

“…The proposed scheme, termed DPTCR, relies on pulse/tone signals to reduce network latency while performing channel reservation. Unfortunately, the above technique cannot be directly applied to 5G mobile wireless networks as the devices are expected to be empowered with full-duplex, omnidirectional antennas [9].…”

The increasing demands for high-data rate traffic stimulated the development of the fifth-generation (5G) mobile networks. The envisioned 5G network is expected to meet its challenge by devising means to further improve spectrum usage. Many alternatives to enhance spectrum usage are being researched, such as massive MIMO, operation in mmWave frequency, cognitive radio, and the employment of full-duplex antennas. Efficient utilization of the potential of any of these technologies faces a set of challenges related to medium access control (MAC) schemes. This work focuses on MAC schemes tailored for full-duplex antennas, since they are expected to play a major role in the foreseeable 5G networks. In this context, this paper presents a MAC layer technique to improve total transmission time when full-duplex antennas are employed. Several evaluations in different scenarios are conducted to assess the proposed MAC scheme. Numerical results show that the proposed scheme provides gains up to 156% when compared to a state-of-the-art full-duplex antenna MAC protocol. Compared to traditional half-duplex antenna MAC protocols, the proposed scheme yields gain up to 412%.

“…Ma et al (2012), the authors use pulse/tone signals to reduce the collision probability of RTS/CTS control frames. Recently, (Guimarães et al, 2015) proposed the use of pulse/tone signaling to reduce the overhead of control frames on IEEE-based MAC protocols. In (Lu et al, 2015), the authors successfully implemented pulse/tone signals on a test-bed using the Microsoft Sora Platform for Cognitive Radios Networks (CRN) (Tan et al, 2009).…”

“…Nevertheless, CRP does not require a prior knowledge on the number of contending stations. Similarly to the works in (Haas and Deng, 2002;Ma et al, 2012;Guimarães et al, 2015), CRP takes advantage of pulse/tone signaling to elect a transmitter among a group of contending stations. To assess the goodness of the proposed scheme, we first consider the case in which the nodes are equipped with collision detection (CD) mechanisms (Tseng et al, 2002).…”

Abstract:Wireless technologies have permeated a significant number of devices over the years. On the other hand, Medium Access Control (MAC) protocols strive to deal with an increasing number of contending nodes on crowded frequency bands. This work presents an efficient medium access control resolution protocol. The proposed protocol, termed Collision Resolution Protocol (CRP), uses pulse/tone signaling that works in both Collision Detection (CD) and Non-Collision Detection (NCD) environments. Given n>1 contending nodes, CRP selects a single transmitting node in 16n and 40n time slots, respectively, for the CD and the NCD scenarios, with probability of at least 1-2 -1.5n . Furthermore, CRP does not require an exact number, or estimation, of the contending nodes.Extensive simulations on the OMNeT++ shows that, for n = 256 and considering CD-capability, CRP successfully grants channel access in 0.03% of the time required by the IEEE 802.11 standard while improving the number of transmissions per second in 100%. In addition, CRP provides fair resource allocation and reduced channel access latency.
