中文摘要：

无线传感器网络有大量应用程序。察觉到范围和通讯范围是服务的二基本质量。在这篇论文，我们在场我们精力上的工作有效察觉到范围和通讯。我们为分别地察觉到范围题目到不同要求和限制设计几个计划。我们也建议基于小世界网络理论为大规模传感器网络与高精力效率和低潜伏扔通讯协议的国外。模拟和实验结果证明我们的计划和协议有好性能。

英文摘要：

Wireless sensor networks have a wide range of applications. Sensing coverage and communication coverage are two fundamental quality of service. In this paper, we present our work on energy efficient sensing coverage and communication. We design several schemes for sensing coverage subject to different requirements and constraints respectively. We also propose a broadcasting communication protocol with high energy efficiency and low latency for large scale sensor networks based on the Small World network theory. Simulation and experiment results show that our schemes and protocol have good performance.
