Performance Enhancement of C-V2X Mode 4 Utilizing Multiple Candidate Single-subframe Resources
G. P. Wijesiri N. B. A, T. Samarasinghe, J. Haapola
Prioritization of data streams in cellular vehicle-to-everything (C-V2X) may lead to unfavorable packet delays in low priority streams. This paper studies the allocation of multipl…
The Effect of Multiple Access Categories on the MAC Layer Performance of IEEE 802.11p
Geeth P. Wijesiri, Jussi Haapola, Tharaka Samarasinghe
The enhanced distributed channel access (EDCA) mechanism enables IEEE 802.11p to accommodate differential quality of service (QoS) levels in vehicle-to-vehicle (V2V) communications…
A Discrete-Time Markov Chain Based Comparison of the MAC Layer Performance of C-V2X Mode 4 and IEEE 802.11p
Geeth P. Wijesiri, Jussi Haapola, Tharaka Samarasinghe
Vehicle-to-vehicle (V2V) communication plays a pivotal role in intelligent transport systems (ITS) with cellular-vehicle to everything (C-V2X) and IEEE 802.11p being the two compet…
Contextual Bandit Learning for Machine Type Communications in the Null Space of Multi-Antenna Systems
Samad Ali, Hossein Asgharimoghaddam, Nandana Rajatheva +2
In this paper, a novel approach based on the concept of opportunistic spatial orthogonalization (OSO) is proposed for interference management between machine type communications (M…
Sleeping Multi-Armed Bandit Learning for Fast Uplink Grant Allocation in Machine Type Communications
Samad Ali, Aidin Ferdowsi, Walid Saad +2
Scheduling fast uplink grant transmissions for machine type communications (MTCs) is one of the main challenges of future wireless systems. In this paper, a novel fast uplink grant…
D2D Communications in LoRaWAN Low Power Wide Area Network: From Idea to Empirical Validation
Konstantin Mikhaylov, Juha Petäjäjärvi, Jussi Haapola +1
In this paper we advocate the use of device-to-device (D2D) communications in a LoRaWAN Low Power Wide Area Network (LPWAN). After overviewing the critical features of the LoRaWAN…
