无线传感器网络覆盖新算法研究

摘要

In practice, many physical parameters are continuous during one period of time, and when monitoring these parameters the traditional WSN algorithms exist many disadvantages such as the irrationality distribution of the nodes, low coverage efficiency, the large computation and so on. This paper puts forward a new algorithm through reference of dynamic nested grid technology used in hydrodynamic. Finally, this algorithm is simulated and the results show that the coverage efficiency, coverage uniformity and the energy efficiency are all improved when the monitor precision is the same.%目前无线传感器网络对时间空间连续分布的物理量进行监测时存在着节点分布不合理,覆盖效率低,网络计算量大等问题.采用流体力学中数值分析的动态嵌套网格技术,设计了一种新的基于动态嵌套网格技术的无线传感器网络覆盖算法.最后对该算法进行仿真实验,结果表明该算法在相同监测精度时所得到的覆盖效率、覆盖均匀性、能效指标等比传统的覆盖算法有所优化.
