We describe a new recommender system for the Russian interactive radio network FMhost. The new recommender model combines collaborative and user-based approaches. The system extracts information from tags of listened tracks for matching user and radio station profiles and follows an adaptive online learning strategy based on user history. We also provide some basic examples and describe the quality of service evaluation methodology.

Wireless Networks are being developed rapidly during the last two decades. Since that time, science and technologies have been modernized from slow GPRS networks to the networks of fourth generation, which are allowed to transfer the data wirelessly at the high speed and relatively low latency. However, the technological progress has not being stopped after ...

Ultra-Reliable Low Latency Communications (URLLC) is an important feature of 5G networks which cannot be enabled without redesigning the architecture of cellular networks. While most activities in 3GPP are focused on developing low-layer functionality, such as modulation and coding schemes, OFDMA numerology, fast hybrid automatic repeat request, in the paper, we study the influence of ...

Historical fragmentation in spectrum access models accentuates the need for novel concepts that allow for efficient sharing of already available but underutilized spectrum. The emerging LSA regulatory framework is expected to enable more advanced spectrum sharing between a limited number of users while guaranteeing their much needed interference protection. However, the ultimate benefits of LSA ...

To improve Wi-Fi performance in scenarios with high collision probability, recent amendments to the Wi- Fi standard introduce a number of channel access methods based on preliminary channel time reservations. A common feature of these methods is that channel time is reserved in a periodic manner. Unfortunately, having defined a number of channel reservation methods, ...

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 ...

Механизм MCCA детерминированного доступа к среде, описанный в стандарте IEEE 802.11s сетей Wi-Fi Mesh, может успешно использоваться в таких сетях для передачи данных с высокими требованиями к качеству обслуживания. Этот механизм позволяет любой станции сети Wi-Fi Mesh зарезервировать последовательность периодических интервалов времени, называемых MCCAOP, в течение которых только эта станция имеет право передавать, а станции ...

Большинство технологий беспроводной связи (например Wi-Fi) позволяют станциям сети заранее зарезервировать канал для передачи своих данных. В частности, широко распространен подход периодических резервирований, когда станция резервирует последовательность периодических интервалов времени одинаковой длительности. Резервирование канала обеспечивает защиту от коллизий, а потому целесообразно при передаче данных, требовательных к качеству обслуживания. Однако ошибки могут возникать вследствие случайных помех, ...

Для передачи по mesh-сети трафика, предъявляющего высокие требования к качеству обслуживания, целесообразно использовать описанный в стандарте IEEE 802.11s механизм MCCA детерминированного доступа к среде. При использовании этого механизма станции резервируют для своих передач определенные периодически повторяющиеся моменты времени, тем самым обеспечивая бесконкурентный доступ к каналу связи. Однако, чтобы обеспечить успешную доставку данных в условиях помех, ...

The IEEE 802.11s standard of Wi-Fi Mesh networking introduces a novel deterministic channel access mechanism called MCCA. This mechanism allows stations to reserve distinct time intervals for their data transmission. Since each station is informed about their neighbouring stations' reservations, it does not transmit during them leading to less packet losses due to packets collisions. ...
