摘要：

This talk starts with a vision for a futuristic multi-tiered network that spans network tiers in the air, on the ground, and under the sea.  We then focus on efficient data collection in the deep sea that poses some unique challenges due to the need for timely data reporting and the delay of acoustic transmission in the ocean. Autonomous underwater vehicles (AUVs) are deployed in the deep sea to surface frequently to transmit collected data from sensors (in a 2D or 3D search space) to the surface stations. However, resurfacing incurs additional delay. Our objective is to minimize the average data reporting delay, through optimizing the number and locations of AUV resurfacing events. We study trajectory planning of AUVs using an extended Euler circuit, where the search space is a set of segments (e.g., oil pipes) in the deep sea. To further reduce data reporting delay, we also explore schemes that schedule multiple AUVs cooperatively. Experiments in both the synthetic and real traces are used to validate the efficiency of the proposed solutions.
