这是一篇关于多传感器网络布站的研究文章，从原理、算法到具体实现，最后是仿真结果分析，层次清晰，分析得当，是一篇值得学习的文章-The prominent visions of wireless sensor networks that appeared about

a decade ago have spurred enormous efforts in research and development of this

new class of wireless networked embedded systems. Despite the significant effort

made, successful deployments and real-world applications of sensor networks are

still scarce, labor-intensive and oftenn cumbersome to achieve. In this article, we

survey prominent examples of sensor network deployments, their interaction with

the real world and pinpoint a number of potential causes for errors and common

pitfalls. In the second half of this work, we present methods and tools to be used

to pinpoint failures and understand root causes. These instrumentation techniques

are specifically designed or adapted for the analysis of distributed networked embedded

systems at the level of components, sensor nodes, and networks of nodes.
