【摘要】：无线传感器网络WSN发射功率的优化调度是决定WSN使用寿命和提高WSN性能的关键,WSN路由节点的在进行数据转发时会导致热点随机扩散,发射功率无法难以实现最大化。提出一种基于路由热点循迹修正的WSN发射功率调度算法。设计了WSN节点路由热点循迹数据传输模型,对发射功率消耗能量模型采用一个高斯衰减信道建模,采用直线反馈线性化补偿方式对路由热点的偏移轨迹进行超负荷状态评估,采用贪婪算法生成一条多分簇路由链,对路由循迹轨迹进行修正,得到WSN优化发射功率的调度递推公式,实现能耗最佳的功率优化调度。实验结果表明,采用该优化调度方法,在准确实现热点循迹修正,传输功率较传统方法稳定,波动较小,WSN可靠性和生存性增强。
[Abstract]:The optimal scheduling of WSN transmission power in wireless sensor networks is the key to determine the lifetime of WSN and improve the performance of WSN. The routing node of WSN will lead to the random diffusion of hot spots during data forwarding, and the transmission power can not be maximized. A WSN transmit power scheduling algorithm based on routing hotspot tracking correction is proposed. WSN node routing hot spot tracking data transmission model is designed. A Gao Si attenuation channel model is used to model the transmission power consumption energy model and the linear feedback linearization compensation method is used to evaluate the overload state of the routing hot spot migration trajectory. The greedy algorithm is used to generate a multi-cluster routing chain, and the routing trace track is modified, and the recursive formula for optimal transmission power scheduling of WSN is obtained, and the optimal power scheduling with the best energy consumption is realized. The experimental results show that the proposed optimal scheduling method is more stable in power transmission and less volatile in reliability and survivability of WSN than the traditional method in the accurate implementation of hot spot tracking correction.
