为优化无线传感器网络中因节点随机部署而产生的覆盖空洞、分布不均及能效低下等问题,提出了一种多策略融合的改进蛇优化算法。首先,采用Tent混沌映射与改进版对立学习策略生成高质量初始种群,以提升初始解的质量。其次,设计了随机-精英交替引导机制,以平衡并增强算法的全局探索能力。随后,在开发阶段引入了量子竞争纠缠与遗传表观调控机制,旨在增强种群多样性并加速收敛。此外,采用动态适应度排名策略以自适应调整选择压力。仿真实验结果表明,与对比算法相比,该新算法在网络覆盖率与节点分布均匀性方面均展现出更优的性能,为解决WSN覆盖优化问题提供了一种有效的解决方案。
To address the issues of coverage holes
uneven distribution
and low energy efficiency caused by random node deployment in Wireless Sensor Networks
an improved Snake Optimizer integrating multiple strategies was proposed. Firstly
Tent chaotic mapping and an improved opposition-based learning strategy were employed to generate a high-quality initial population. Secondly
a random-elite alternating guidance mechanism was designed to enhance the exploration capability of the algorithm. Subsequently
quantum competitive entanglement and genetic epigenetic regulation mechanisms were introduced during the exploitation phase to increase population diversity and improve convergence. Furthermore
a dynamic fitness ranking strategy was adopted to adaptively adjust the selection pressure. Simulation results demonstrated that the proposed algorithm outperformed other compared algorithms in terms of both coverage rate and distribution uniformity
thereby providing an effective solution for WSN coverage optimization.
