“…To reduce network overhead due to topology information broadcasting, methods for avoiding resource collision without broadcasting one-hop information have been proposed in [12]- [14], [21], [24], [25], [35]. Reference [25] provides a method for removing hidden nodes in a unicast link, where the frame is divided into CP (competition period) and CFP (competition free period).…”

This paper proposes an evolved wireless ad hoc network (WANET) in which user equipment (UE) can manage radio resources by itself without the control by infrastructure. There are two independent channels in the proposed WANET, one is a data channel, the other is a tone channel for resource management. UEs allocate, occupy, and return resources by using tones in the tone channel. Although UEs do not exchange channel information with each other, they are able to occupy a clear one-hop area without a hidden node problem by setting the data communication area and the tone communication area differently. A UE occupying a resource performs a real time collision check on the occupied resource, and if a collision is detected, it is able to re-occupy a resource without collision. In this paper, we present the operating principle of the proposed WANET, and design its communication area, and analyze the average resource occupation time. Since the proposed WANET operates in a general communication environment that is not limited to special assumptions, it supports periodic and aperiodic communication and broadcast links and unicast links without hidden node problem, and could be utilized to various communication fields such as drones, vehicles, ships, and smartphones.INDEX TERMS Ad hoc networks, hidden node, medium access control, packet collision resolution.

“…Many alternative MAC protocols have been proposed to improve the performance of standard MAC protocol [16][17][18][19][20][21][22][23][24][25][26][27][28]. The authors of [16] proposed a multichannel TDMA MAC protocol called VeMAC.…”

“…An interesting study was conducted in [23] in order to enhance the reliability of onehop broadcast (beacon) packet transmission. The authors of [23] divided OFDM channels of DSRC band into subframes and subchannels, wherein the smallest radio resource is called basic resource unit (resource in time and frequency domain). To allocate the basic resource units, the authors proposed two allocation protocols: centralized and distributed resource allocation MAC protocols.…”

IEEE 1609/802.11p standard obligates each vehicle to broadcast a periodic basic safety message (BSM). The BSM message comprises a positional and kinematic information of a transmitting vehicle. It also contains emergency information that is to be delivered to all the target receivers. In broadcast communication, however, existing carrier sense multiple access (CSMA) medium access control (MAC) protocol cannot guarantee a high reliability as it suffers from two chronic problems, namely, access collision and hidden terminal interference. To resolve these problems of CSMA MAC, we propose a novel enhancement algorithm called a neighbor association-based MAC (NA-MAC) protocol. NA-MAC utilizes a time division multiple access (TDMA) to distribute channel resource into short time-intervals called slots. Each slot is further divided into three parts to conduct channel sensing, slot acquisition, and data transmission. To avoid a duplicate slot allocation among multiple vehicles, NA-MAC introduces a three-way handshake process during slot acquisition. Our simulation results revealed that NA-MAC improved packet reception ratio (PRR) by 19% and successful transmission by 30% over the reference protocols. In addition, NA-MAC reduced the packet collisions by a factor of 4. Using the real on-board units (OBUs), we conducted an experiment where our protocol outperformed in terms of PRR and average transmission interval by 82% and 49%, respectively.
