Optimal and Quantized Mechanism Design for Fresh Data Acquisition
Meng Zhang, Ahmed Arafa, Ermin Wei +1
The proliferation of real-time applications has spurred much interest in data freshness, captured by the {\it age-of-information} (AoI) metric. When strategic data sources have pri…
A fixed-point model for semi-persistent scheduling of vehicular safety messages
Xu Wang, Randall A. Berry, Ivan Vukovic +1
In this paper, we focus on the performance analysis of a semi-persistent scheduling scheme for vehicular safety communications, motivated by the Mode 4 medium access control protoc…
Competitive Resource Allocation in HetNets: the Impact of Small-cell Spectrum Constraints and Investment Costs
Cheng Chen, Randall A. Berry, Michael L. Honig +1
Heterogeneous wireless networks with small-cell deployments in licensed and unlicensed spectrum bands are a promising approach for expanding wireless connectivity and service. As a…
Coordination protocol for inter-operator spectrum sharing in co-primary 5G small cell networks
Bikramjit Singh, Sofonias Hailu, Konstantinos Koufos +4
We consider spectrum sharing between a limited set of operators having similar rights for accessing spectrum. A coordination protocol acting on the level of the Radio Access Networ…
Co-primary inter-operator spectrum sharing over a limited spectrum pool using repeated games
Bikramjit Singh, Konstantinos Koufos, Olav Tirkkonen +1
We consider two small cell operators deployed in the same geographical area, sharing spectrum resources from a common pool. A method is investigated to coordinate the utilization o…
