“…Research work [12,[32][33][34][35][36][37] focuses on model the throughput performance in wireless networks. The interference caused by rogue APs are modeled in [32], the authors find that hidden terminals cause about 30% MAC layer loss rate increase on average, and the carrier sense interference due to rogue APs causes only 5% access delay to increase at the MAC layer.…”

“…Research works in [27] aim to model the packet delay caused by interference, and the author proposed an algorithm to minimize the interference and decrease the packet latencies. The compound TCP in the Internet of Thing (IoT) is modeled as several subprocesses in [37]; these subprocesses are congestion window, throughput, and packet loss.…”

Data transmissions suffer from TCP’s poor performance since the introduction of the first commercial wireless services in the 1990s. Recent years have witnessed a surge of academia and industry activities in the field of TCP performance optimization. For a TCP flow whose last hop is a wireless link, congestions in the last hop dominate its performance. We implement an integral data sampling, network monitoring, and rate control software-defined wireless networking (SDWN) system. By analysing our sampled data, we find that there exist strong relationships between congestion packet loss behaviors and the instant cross-layer network metric measurements (states). We utilize these qualitative relationships to predict future congestions in wireless links and enhance TCP performance by launch necessary rate control locally on the access points (AP) before the congestions. We also implement modeling and rate control modules on this platform. Our platform senses the instant wireless dynamic and takes actions promptly to avoid future congestions. We conduct real-world experiments to evaluate its performance. The experiment results show that our methods outperform the bottleneck bandwidth and RTT (BBR) protocol and a recently proposed protocol Vivace on throughput, delay, and jitter performance at least 16.5%, 25%, and 12.6%, respectively.

“…A large number of papers have studied the performance of TCP and ECN; see [8,[19][20][21] as a not exhaustive list, but the main focus is on the behavior of a single TCP connection under various scenarios. Other works focused on the specific TCP versions installed by default in the Linux and Windows operating systems and developed models studying their performance [22][23][24]. More similar to the analysis carried out here are those proposed in [9,25,26] where the authors consider the overall system performance in the mean field limit for ECN/RED.…”

We consider the scenario in which several TCP connections share the same access point (AP) and a congestion avoidance/control mechanism is adopted with the aim of assigning the available bandwidth to the clients with a certain fairness. When UDP traffic with real-time requirements is present, the problem becomes even more challenging. Very well-known congestion avoidance mechanisms are the Random Early Detection (RED) and the Explicit Congestion Notification (ECN). More recently, the Smart Access Point with Limited Advertised Window (SAP-LAW) has been proposed. Its main idea is that of computing the maximum TCP rate for each connection at the bottleneck, taking into account the UDP traffic to keep a low queue size combined with a reasonable bandwidth utilization. In this paper, we propose a new congestion control mechanism, namely, Smart-RED, inspired by SAP-LAW heuristic formula. We study its performance by using mean field models and compare the behaviours of ECN/RED, SAP-LAW, and Smart-RED under different scenarios. We show that while Smart-RED maintains some of the desirable properties of the SAP-LAW, it solves the problems it may have in case of bursty UDP traffic or TCP connections with very different needs of bandwidth.

“…Hence, wireless access technology providing reliable communications is the key to unleash the potential of the massive IoT. Currently, IoT devices access various wireless networks mainly via low-cost commercial technologies such as Zigbee [8], Bluetooth [9], and WiFi [10]. However, these technologies only support short-range wireless access for a an indoor environment or in a small area.…”

Massive access, also known as massive connectivity or massive machine-type communication (mMTC), is one of the main use cases of the fifth-generation (5G) and beyond 5G (B5G) wireless networks. A typical application of massive access is the cellular Internet of Things (IoT). Different from conventional human-type communication, massive access aims at realizing efficient and reliable communications for a massive number of IoT devices. Hence, the main characteristics of massive access include low power, massive connectivity, and broad coverage, which require new concepts, theories, and paradigms for the design of next-generation cellular networks. This paper presents a comprehensive survey of aspects of massive access design for B5G wireless networks. Specifically, we provide a detailed review of massive access from the perspectives of theory, protocols, techniques, coverage, energy, and security. Furthermore, several future research directions and challenges are identified.
