LTE-M, which is an abbreviated version of LTE-MTC(Machine Type Communication) can be said to have a variety of applications, including a large number of heterogeneous interconnection of large-scale network equipment. One of the most prominent problems is that the machines may have a large amount of access requests in a short time, which can easily lead to network congestion. At present, the contention-based...
As an essential part of Multi-channel MAC protocol, the channel scheduling algorithm aims at enhancing the network throughput and resource utilization. Based on the WAVE standard in vehicular communications, this paper improves WAVE MAC by using the time division access on service channels and proposes a channel scheduling scheme to negotiate and allocate the channel resources for throughput-sensitive...
Fast reservation list-to-send (FRLS) medium access control (MAC) protocol is proposed to apply to wireless networks with long propagation delay. In the protocol, a central control node (CCN) is applied to allocate the channel resources of two channels, and all the nodes transmit packets over the two channels without collision. Packet train transmission mechanism ensures that a number of packets are...
