Talk-25: Goby-Acomms (including pAcommsHandler) Version 2: An Update on Acoustic Networking for Robotic Marine Platforms
Toby Schneider, MIT, Laboratory for Autonomous Marine Sensing Systems (LAMSS), and Center for Ocean Engineering
Goby-Acomms (including the MOOS interface application "pAcommsHandler") provides a complete "slow-link" networking package for use on links much slower (in both latency and throughput) than many commonly encountered terrestrial channels. As the name suggests this is useful for acoustic communications (such as with the WHOI Micro-Modem) but also with other very low bandwidth / very high latency links (e.g. satellite comms).
This talk will focus on the changes since MOOS-DAWG 2010 which include:
- Use of Google Protocol buffers instead of XML for the Dynamic Compact Control Language (DCCL) schema.
- Use of completely customizable callbacks for encoding / decoding DCCL types
- More comprehensive support for the WHOI Micro-Modem ranging capabilities
- Full support for extending Goby-Acomms to use other acoustic modems.
