Context-Aware Energy-Efficient Matching for Resource Allocation in D2D Communications

content caching, D2D communication, energyefficient, stable matching

In this paper, content caching of popular files in
cellular users is studied to reduce the load of base station and
ensure the efficiency of D2D communications. In particular, we
study a resource allocation to maximize the energy efficiency (EE)
of overall system with considering the actual traffic demands of
D2D users. We apply the D2D users (DUs) and cellular users
(CUs) deferred acceptance algorithm to find stable matchings of
DUs and CUs based on preference lists between DUs and CUs.We
calculate EE in a interference limited environment by employing
the nonlinear fractional programming. Then the optimization
problem is solved by the matching problem under complete
preference lists. Simulation results show that the proposed stable
matching algorithm enables an efficient performance gains.
