A Hybrid Noncooperative Game Model for Wireless Communications

摘要: We investigate a hybrid noncooperative game motivated by the practical problem of joint power control and base station (BS) assignment in code division multiple access (CDMA) wireless data networks. model integrated BS such that each mobile user’s action space includes not only transmission level but also respective choice. Users are associated with specific cost functions consisting logarithmic user preference function terms service levels convex pricing to enhance overall system performance limiting interference preserving battery energy. study existence uniqueness properties pure strategy Nash equilibrium solutions game, which constitute operating points for underlying network. Since this task cannot be accomplished analytically even simplest cases due nonlinear complex nature reaction mobiles, we conduct analysis numerically using grid methods randomized algorithms. Finally, simulate dynamic update scheme, compare it “classical” algorithms aggregate signal-to-interference ratio obtained users.
