Abstract:The Earth is a blue planet. Approximately 71% of the Earth’s surface is coveredby ocean, which corresponds to an area of 361 million km2 and avolume of 1.3 billion km3. Most of this vastness is unexplored andremains a mystery. To address the vision of Anywhere Networking, a newframework needs to be developed in order to leverage the full potential ofunderwater sensor networks by adapting and exploiting the intrinsic propertiesof the underwater environment. In this talk, we will discuss various designissues and practical solutions towards robust, adaptive, and low-latencyunderwater acoustic sensor networks. Topics will cover effective and efficienttransceiver design resolving the Doppler effects inevitable underwater,relay-aided underwater acoustic communications with improved power/spectrumefficiency, and dynamic spatial reuse designs boosting the network throughput.
报告摘要：我们所居住的地球有将近71%的面积被海洋覆盖，这个蓝色星球有着三亿六千一百万平方千米，相当于十三亿立方公里的海洋。在广袤无垠的海洋世界里，还有很大一部分是人类从未探索过的神秘之地。为了达到泛在网络的愿景，我们需要通过适应和探索水下环境的本质，研究并提出新的框架去充分挖掘水下传感器网络蕴含的潜力。本次讲座中，杨教授将阐述在建立具有鲁棒性，适应性，低延时特点的水下声传感器网络设计中存在的问题和实际解决方法。讲座包括以下内容：如何通过有效且有效率地设计收发机来解决水下多普勒效应问题，如何更高能效地进行中继水下声通信，如何设计动态的重复利用空间来提高网络吞吐量。
