Coalitional game based resource allocation in D2D-enabled V2V communication

The joint resource block (RB) allocation and power optimization problem is studied to maximize the sum-rate of vehicle-to-vehicle (V2V) links in device-to-device (D2D)-enabled V2V communication system, where one feasible cellular user (FCU) can share its RB with multiple pairs. first formulated as a nonconvex mixed-integer nonlinear programming (MINLP) constraint maximum interference FCU links. Using game theory, two coalition formation algorithms are proposed accomplish link partitioning selection, transferable utility functions introduced minimize among for optimal allocation. successive convex approximation (SCA) used transform original into Lagrangian dual method further applied obtain transmit Finally, numerical results demonstrate efficiency algorithm terms system sum-rate.
