基于区域差异化的WSNs能效优化研究

Study of WSNs Energy Efficiency Optimization Based on Regional Differentiation

摘要:

随着“互联网 ”概念进一步加深,无线传感器网络(WSNs)技术也得到飞速发展,目前在环保、工业、军事等领域均有大量涉及,而能效问题一直是WSNs发展中重要的制约因素。文章对原有面向簇集的WSNs中存在的簇头能量损失过快的问题进行分析,发现该问题主要由节点过量转发数据所引起,因此从簇内和簇间两部分入手,并对路由策略进行了改进,将网络划分为热点和非热点区域,动态调整区域覆盖范围,结合虚拟多输入输出(VMIMO)和路由跨跳技术减少不必要的节点中继,最后对该方案进行仿真测试,发现改进后的方案可以更加有效地平衡优化WSNs内系统能量损耗。

Abstract:

As the “Internet plus” concept deepens, wireless sensor networks (WSNs) technology has also been developed rapidly, which is heavily involved in environmental protection, industry, military and other fields while the issue of energy efficiency has been the vital constraints in the development of WSNs. This paper analyzed the problem of excessive loss of cluster energy in original WSNs facing cluster and found that this problem arose from the data excessively transmitted by node. Therefore, the study, starting from intra-cluster and inter-cluster parts, changed the routing strategy, regulated the regional coverage area dynamically, reduced the unnecessary node relaying combining with VMIMO and route crossing technology, and lastly made simulating test on the program so as to find the improved scheme and balance the energy consumption of WSNs more effectively.
