Channel access procedures of the state-of-the-art cellular standards create a significant overhead for small messages transmitted by Internet of Things (IoT) devices. As IoT becomes a major source of traffic for next-generation wireless communications, there are recent efforts to design low-overhead access schemes. Here we present the delay and capacity analysis of two low-overhead access protocols...
Cognitive radio (CR) networks are expected to offer a huge bandwidth to wireless users through dynamic spectrum access techniques. To realize this new network paradigm, effective distributed coordination schemes to exchange control information without assuming the availability of a prespecified common control channel (CCC) are needed. In this paper, we propose a distributed group-based spectrum-aware...
According to the different demand on realtime of periodic and non-periodic data, the improved real time communication protocol CSMA/NT is presented with node transfer based on non-destroyed priority bit-by-bit arbitration. The performance analysis shows that it decreases the probability of data collision effectively, ensures a limited transmission time and makes maximum delay time adjustable, leads...
