The document presents a wireless optical communication and localization system for underwater wireless sensor networks. It describes a node design with multiple optical transceivers for omni-directional communication and automatic switching to maintain reliable data transmission as nodes move. Each transceiver has two photodiodes to detect signal strength for distance estimation and 2D node localization calculation. The system enables underwater wireless optical communication at data rates up to several hundred kbps and localization accuracy within 5% of the measured distance.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

The Design and Implement of an Underwater Wireless Optical Communication and
Localization System
Luo Linfeng, Wang Shuo
Complex System and Intelligent Science Lab, Institute of Automation, CAS, Beijing
E-mail: lfeng.luo@yahoo.com
Abstract: In this paper, a node’s wireless optical communication module scheme for underwater wireless sensor
networks is presented and partly realized. And a distance measurement and 2-Dimension localization algorithm is
integrated in the scheme. The module scheme has the following features: the module consists of multiple optical
transceivers for omni-direction communication; it can keep data transmission reliable by automatically switching the
transceivers in case of nodes’ relative position change. Two photodiodes, which detect the optical signal strength for
distance estimation, are installed on each transceiver. The 2-Dimension relative positioning among nodes can be
calculated by the detected optical signal strength of the photodiodes.
Keywords: wireless optical communication, underwater, distance measurement, localization
