A Significant Gain on Improving the Links with Co-operative Transmission And Successive Interference Cancellation

In this paper, we address link maximum activation problem in wireless networks, when sources can perform helpful transmission, and the receivers can perform successive interference cancellation. We provide a full tractability analysis, showing the NP-hardness as well as identifying tractable cases. We position integer linear programming for achieving global optimum using off-the-shelf optimization methods. And last to overcome the scalability issue of integer programming. We design a sub-optimal but efficient optimization algorithm for the problem in its general form, by embedding maximum biased two-part matching into local search. To improve the performance of maximum link connected and activated simultaneously. The objective, to be accurate, is not to maximize the number of active links, but to simultaneously deliver messages successfully to as many receivers as possible. Mathematical results are presented for performance evaluation, to validate the benefit of cooperative transmission and interference cancellation for maximum link activation and to establish the success of the proposed algorithm.
