Hybrid CSMA/CA and HCCA uplink medium access control protocol for VLC based heterogeneous users

“…Table 1 summarizes the simulation environment for the HCCA MAC protocol for PCD and IoT users. The packet size (L p ) for the PCD and IoT users are 400 bytes and 10 bytes according to the video streaming and smart sensing applications, respectively [35]. The slot time [20], ACK time, sets of packets, and data rate are listed in Table 1 for the HCCA MAC protocol.…”

Measurement-based Admission Control in Sliced Networks: A Best Arm Identification Approach

“…Conversational Voice has a packet frequency of about 50 packets/s [22]. Conversational video sends a bitrate of about 1500 kbps [23] and has a packet size of about 1500 bytes [24] which translates to a packet frequency of about 125 packets per second. Finally, Live Gaming has a typical packet interarrival time of 40 ms which translates to 25 packets/s [25].…”

An Algorithm for Detecting Wireless Communication Attacks on Intelligent Vehicles Based on Air Interface Identification

“…For the monitoring of wireless communication attacks, existing technical methods include obtaining mobile communication traffic data in a specific region through a mobile network operator and performing analysis, such as obtaining downlink network traffic, port number, and resource allocation information in a specific region on the base station side, and detecting abnormal steganographic transmission behaviour through a traffic identification model. Typical schemes include port number-based analysis, which completes traffic type [4], protocol analysis [5] anomaly detection [6] based on port rules developed by the Internet Corporation for Assigned Names and Numbers , which is low in computational complexity but gradually loses its effectiveness with the popularity of port obfuscation and forwarding techniques [7]. Subsequently, researchers used Deep Packet Inspection (DPI) method to analyse and match the traffic datagrams to distinguish different flows [8], the algorithm has high accuracy but high computational complexity, and with the update of encryption protocols, the administrators are gradually ISSN 2616-5775 Vol.…”
