“…To improve the uplink delay in WLANs, Lv et al [140] propose a novel MAC scheme referred to as request-based poll access (RPA). The authors of [140] consider a single AP communicating wirelessly with multiple hubs. The proposed scheme is based on a slotted approach, where the time is divided into multiple beacon intervals.…”

“…This work does not cover the ultra-high reliability criterion (C 2 ). We note that the RPA scheme proposed in [140] has some drawbacks. These occur mainly because during the PP, the AP polls all hubs sequentially according to the order of the assigned slots in the RUP without considering the buffer status of each hub.…”

“…Given that this work only considers the uplink delay without mentioning other delay components, this work partially meets the ultra-low latency criterion (C 1 ). Similar to [138] and [140], the reliability aspect has not been discussed in this work and therefore it does not cover the ultra-high reliability criterion (C 2 ).…”

“…Another insight on WLAN and WBAN resource allocation is that none of the studies has addressed the reliability aspect that is also critical for Tactile Internet applications, as discussed in Section II.C. We note that although most of the proposed algorithms rely on contention-free mechanisms [138] [140][141] to avoid packet collision, packet loss can still occur due to erroneous transmission caused by excessive path loss, given that packet dropping occurs mainly due to buffer overflow [139] [143]. The lesson we can infer from this is that the reliability aspect of the WLAN and WBAN technologies must be further investigated in order to fulfill the Tactile Internet reliability requirement.…”

“…Therefore, one promising research direction is the joint design of resource allocation in both uplink and downlink directions for WLANs/WBANs. Toward this end, reference [140] can be used as a starting point, as it proposes a novel MAC scheme for the uplink direction in WLANs relying on an efficient polling-based mechanism to achieve low latency. This scheme could be extended to assign resources for both uplink and downlink transmission simultaneously while ensuring the achievable sum of uplink and downlink delays within 1 ms.…”

The Internet has made several giant leaps over the years, from a fixed to a mobile Internet, then to the Internet of Things, and now to a Tactile Internet. The Tactile Internet goes far beyond data, audio and video delivery over fixed and mobile networks, and even beyond allowing communication and collaboration among things. It is expected to enable haptic communications and allow skill set delivery over networks. Some examples of potential applications are telesurgery, vehicle fleets, augmented reality and industrial process automation. Several papers already cover many of the Tactile Internet-related concepts and technologies, such as haptic codecs, applications, and supporting technologies. However, none of them offers a comprehensive survey of the Tactile Internet, including its architectures and algorithms. Furthermore, none of them provides a systematic and critical review of the existing solutions. To address these lacunae, we provide a comprehensive survey of the architectures and algorithms proposed to date for the Tactile Internet. In addition, we critically review them using a well-defined set of requirements and discuss some of the lessons learned as well as the most promising research directions.

The multimedia Tactile Internet is a network that provides ultra-low latency and ultra-high reliability for two-way multimedia services. Since random access in uplink dominates the delay and there exist variations of target delays among connections, it is much more efficient to perform a joint uplink and downlink resource allocation. In this paper, we provide uplink random access schemes with joint uplink/downlink resource allocation using multichannel architecture for multimedia Tactile Internet.By doing so, one can significantly increase the resource utilization efficiency and improve the reliability of the multimedia Tactile Internet as well. The cores of the resource management are two-fold. First, the joint resource allocation dynamically adjusts the ratio of the number of uplink channels and the number of downlink channels and performs access control based on the collision ratio and the queue lengths. Secondly, the efficient uplink random access increases the throughput, where each transmitting node selects a number of time slot/channel pairs based on either the Finite Projective Plane, the random numbers, or the hybrid. In the performance evaluation, we compare the performance of different selections for the multichannel architecture in terms of throughput for the multimedia Tactile Internet through simulation runs and analysis. The hybrid selection scheme performs the best since it 2 has the advantages of both the Finite Projective Plane structure and being random.
