An Improved Sparrow Algorithm Based on Small Habitats in Cooperative Communication Power Allocation

To solve the power allocation problem of multiple relays in cooperative communication, a sparrow improvement algorithm based on small habitats is proposed. First, small-habitat rule increases diversity energy classification communication nodes. The premature convergence solved. Subsequently, joint jump designed to replace local search rule, and modified avoid wandering phenomenon. improved method solves solution most available function. Lastly, validation experiment performance carried out according IEEE CEC 2017 benchmark document set. simulation verifies practicality various algorithms. maximum evaluation number (max FE) objective function calculated compare experimental results show that can increase species. multi-point capability global merit are improved. Additionally, speed computational accuracy effective controlling collaborative communication. control has some practicality. Friedman Wilcoxon test criteria applied shown be higher than those other This indicates
