中文摘要：
从无线传感器网络（WSN）环境数值监测应用的实际需求出发，提出了一种应用于该类场景中的等值线绘制（CMBC）算法。CMBC算法基于图形学中常用的贝塞尔（Bezier）曲线理论，通过选择部分节点提供信息给网关节点绘制等值线。此方法有效解决了监测应用场景中对最终监测精度的需求与大量报告节点所引发的高流量负载和网络能耗之间的矛盾。仿真结果表明，CMBC算法和已有研究工作相比能够使用更少的汇报节点完成高精度等值线的绘制，因此CMBC算法能够节省节点的能量．延长网络的生存期。
英文摘要：
From the perspective of actual environmental monitoring demand in wireless sensor networks （WSNs）, the paper puts forward an algorithm for contour mapping based on Bezier curves （CMBC） in these scenarios. The CMBC algorithm is based on the theory of Bezier curves and is widely used in computer graphics. It selects part of nodes to send contour mapping information to sink. In monitoring scenarios, the CMBC algorithm effectively solves the conflicts between demand of precision and transmission restraint, high energy consumption caused by nodes increasing. The comprehensive simulation results show that the CMBC algorithm achieves a high fidelity of contour mapping by using much fewer nodes as data sources than existing works, so the algorithm can save the limited energy of nodes and extend network life.
