Scheduling Out-of-Coverage Vehicular Communications Using Reinforcement Learning
Taylan Şahin, Ramin Khalili, Mate Boban +1
Performance of vehicle-to-vehicle (V2V) communications depends highly on the employed scheduling approach. While centralized network schedulers offer high V2V communication reliabi…
Generation of Realistic Cloud Access Times for Mobile Application Testing using Transfer Learning
Manoj R. Rege, Vlado Handziski, Adam Wolisz
The network Quality of Service (QoS) metrics such as the access time, the bandwidth, and the packet loss play an important role in determining the Quality of Experience (QoE) of mo…
Distributed Learning for Proportional-Fair Resource Allocation in Coexisting WiFi Networks
Piotr Gawłowicz, Jean Walrand, Adam Wolisz
In this paper, we revisit the widely known performance anomaly that results in severe network utility degradation in WiFi networks when nodes use diverse modulation and coding sche…
OfdmFi: Enabling Cross-Technology Communication Between LTE-U/LAA and WiFi
Piotr Gawłowicz, Anatolij Zubow, Suzan Bayhan +1
Despite exhibiting very high theoretical data rates, in practice, the performance of LTE-U/LAA and WiFi networks is severely limited under cross-technology coexistence scenarios in…
VRLS: A Unified Reinforcement Learning Scheduler for Vehicle-to-Vehicle Communications
Taylan Şahin, Ramin Khalili, Mate Boban +1
Vehicle-to-vehicle (V2V) communications have distinct challenges that need to be taken into account when scheduling the radio resources. Although centralized schedulers (e.g., loca…
Reinforcement Learning Scheduler for Vehicle-to-Vehicle Communications Outside Coverage
Taylan Şahin, Ramin Khalili, Mate Boban +1
Radio resources in vehicle-to-vehicle (V2V) communication can be scheduled either by a centralized scheduler residing in the network (e.g., a base station in case of cellular syste…
Greedy Multi-Channel Neighbor Discovery
Niels Karowski, Konstantin Miller, Adam Wolisz
The accelerating penetration of physical environments by objects with information processing and wireless communication capabilities requires approaches to find potential communica…
Towards efficient coexistence of IEEE 802.15.4e TSCH and IEEE 802.11
Mikołaj Chwalisz, Adam Wolisz
A major challenge in wide deployment of smart wireless devices, using different technologies and sharing the same 2.4 GHz spectrum, is to achieve coexistence across multiple techno…
Coexistence Gaps in Space: Cross-Technology Interference-Nulling for Improving LTE-U/WiFi Coexistence
Suzan Bayhan, Anatolij Zubow, Adam Wolisz
To avoid the foreseeable spectrum crunch, LTE operators have started to explore the option to directly use 5 GHz unlicensed spectrum band being used by IEEE 802.11 (WiFi). However,…
LtFi: Cross-technology Communication for RRM between LTE-U and IEEE 802.11
Piotr Gawłowicz, Anatolij Zubow, Adam Wolisz
Cross-technology communication (CTC) was proposed in recent literature as a way to exploit the opportunities of collaboration between heterogeneous wireless technologies. This pape…
Towards LTE-U Interference Detection, Assessment and Mitigation in 802.11 Networks using Commodity Hardware
Michael Olbrich, Anatolij Zubow, Sven Zehl +1
We propose WiPLUS -- a system that enables WiFi to deal with the stealthy invasion of LTE-U into the frequency bands used by WiFi. Using solely MAC layer information extracted pass…
