Query: Optimal Radio Resource Allocation for Hybrid Traffic in Cellular
  Networks: Centralized and Distributed Architecture   Optimal resource allocation is of paramount importance in utilizing the
scarce radio spectrum efficiently and provisioning quality of service for
miscellaneous user applications, generating hybrid data traffic streams in
present-day wireless communications systems. A dynamism of the hybrid traffic
stemmed from concurrently running mobile applications with temporally varying
usage percentages in addition to subscriber priorities impelled from network
providers' perspective necessitate resource allocation schemes assigning the
spectrum to the applications accordingly and optimally. This manuscript
concocts novel centralized and distributed radio resource allocation
optimization problems for hybrid traffic-conveying cellular networks
communicating users with simultaneously running multiple delay-tolerant and
real-time applications modelled as logarithmic and sigmoidal utility functions,
volatile application percent usages, and diverse subscriptions. Casting under a
utility proportional fairness entail no lost calls for the proposed modi
operandi, for which we substantiate the convexity, devise computationally
efficient algorithms catering optimal rates to the applications, and prove a
mutual mathematical equivalence. Ultimately, the algorithms performance is
evaluated via simulations and discussing germane numerical results.
