Power Allocation for 5G Mobile Multiuser Cooperative Networks

With the fifth generation (5G) communication technology, the mobile multiuser networks have developed rapidly. In this paper, the performance analysis of mobile multiuser networks which utilize decode-and-forward (DF) relaying is considered. The authors derive novel outage probability (OP) expressions. To improve the OP performance, the authors study the power allocation optimization problem. To solve the optimization problem, the authors propose an intelligent power allocation optimization algorithm based on grey wolf optimization (GWO). The authors compare the proposed GWO approach with three existing algorithms. The experimental results reveal that the proposed GWO algorithm can achieve a smaller OP, thus improving system efficiency. Also, compared with other channel models, the OP values of the 2-Rayleigh model are increased by 81.2% and 66.6%, respectively.
