Optimization of computation and bandwidth resource allocation for deployed services

Determine optimal values for the computation resources f_m^{j,t} allocated by each edge server m to each deployed service j and the scheduling bandwidth R_{m,m'}^{j,t} allocated for tasks of service j from edge server m to edge server m' in each large-timescale frame t, rather than modeling these quantities as fixed functions of the service deployment decisions d_m^{j,t}.

Background

In the service deployment model, the paper introduces decision variables for computation resources f_m^{j,t} allocated to each deployed service and inter-edge-server scheduling bandwidth R_{m,m'}^{j,t}. These variables directly affect task processing delay but, to focus the paper on joint service deployment and task scheduling, they are not optimized; instead, they are modeled as functions of the deployment decisions.

The authors explicitly state that optimizing these resource allocation strategies is deferred, indicating a specific unresolved component needed to complete the overall optimization framework for minimizing expected processing delay in mobile edge computing networks.
