We describe the design, manufacture, and deployment of advanced wildlife tracking tags (transmitters) based on integrated transceivers. The tags weigh as little as 2g and cost less than $20 each in relatively small quantities (tens).
We describe software-engineering lessons we learned by building, deploying, and operating a large-scale distributed wildlife tracking system. The design started four years ago, the system has been operational for the past two years, but kept evolving during this time. The paper describes the structure of the system and then a series of interesting and… (More)
—Mobile devices use low-cost SSDs such as microSD cards and eMMC devices for persistent data storage. However, The controllers of low-cost SSDs are optimized for reads and for sequential writes and they perform poorly under random writes. In this paper, we show that it is possible to overcome this limitation using a novel device driver on the host. Our… (More)
