摘要: 针对监测区域内含有障碍物的无线传感器网络(Wireless Sensor Networks,WSNs)异构节点部署优化问题,在花朵授粉算法(Flower Pollination Algorithm,FPA)的基础之上,提出了一种改进的花朵授粉算法(Improved Flower Pollination Algorithm,IFPA)用于改善原有算法收敛速度慢、精度不够高的不足。设计非线性收敛因子以约束原有的缩放因子,采用Tent映射以维持迭代后期种群的多样性,而贪心交叉策略则是以较优的个体辅助较差个体搜索。基准函数实验验证了IFPA具有较好的收敛性能,而WSN部署的仿真实验表明IFPA可得到较高的覆盖率,可节约网络部署成本。

Abstract: To optimize the coverage problem of wireless sensor networks (WSNs) Heterogeneous nodes with obstacles in the monitoring area, based on the flower pollination algorithm (FPA), an improved flower pollination algorithm (IFPA) is proposed. IFPA is used to improve the shortcomings of the original algorithm with slow convergence speed and low precision. The nonlinear convergence factor is designed to constrain the original scaling factor, the Tent mapping is used to maintain the diversity of the population in the late iteration, and the greedy crossover strategy is used to assist the poor individuals to search with better individuals. The experiment of the benchmark function proves that the IFPA has a better convergence performance than other comparison algorithms, and the simulation experiments of WSN deployment show that IFPA can obtain a higher coverage rate and save network deployment cost.
