Modelling Deterministic Channel Access in Millimetre Wave Wi-Fi
.
Due to the scarcity of license exempt spectrum at low frequencies, next generation multi-gigabit wireless communication will use 60 GHz. Propagation characteristics make impossible to use omnidirectional high-rate low-power transmission at long distances. As for directional transmission, it cannot be efficient with random channel access while the usage of deterministic one even in the state-of-the-art 60 GHz technologies --- e.g. IEEE 802.11ad --- raises a question of how much channel time shall be allocated for a stream to satisfy its QoS requirement. The main contribution of the paper is the mathematical model of Constant Bit Rate (CBR) flow transmission in IEEE 802.11ad networks, which allows to answer this question.

Introduction: Caching reduces content access latency by bringing it closer to users and offloading the cloud layer of the network. Edge servers are used for this purpose, but the standard TCP/IP stack does not fully utilize caching capabilities. Therefore, it is necessary to consider a cache model using the Named Data Networking stack, which is ...

A key feature of 5G systems is the Ultra-Reliable Low-Latency Communication (URLLC), which can be used for remote surgery, smart grids, industrial control, etc. URLLC requires millisecond-level delays and very high reliability, i.e., less than 10−5 packet loss probability. The ability to satisfy these very strict quality of service requirements depends on selecting the Modulation and Coding ...
