 uMesh is a set of experimental communication protocols intended mainly for low data rate wireless mesh networks such as sensor networks for environmental data gathering, asset and people tracking, short message delivery and paging, narrowband voice communication etc. in scenarios, where common network infrastructure is not reachable and/or is not feasible for a particular purpose. Protocols are designed with high level of security in mind which could make them suitable for many critical and disaster recovery applications in the future. uMesh is a set of experimental communication protocols intended mainly for low data rate wireless mesh networks such as sensor networks for environmental data gathering, asset and people tracking, short message delivery and paging, narrowband voice communication etc. in scenarios, where common network infrastructure is not reachable and/or is not feasible for a particular purpose.

It also makes "​redrawing"​ screen and user interface widgets easier - there is no need to actively redraw anything after changes. A simple display list rendering library.

 This is an attempt to specify an extensible platform in the hope that it will be useful. A platform built by electronic engineers and enthusiasts for researchers in environmental sciences for nature observation and monitoring. A platform, where the actual user is not required to have soldering skills, does not have to download arduino.exe and handcraft some code, where the devices are able to withstand severe environmental conditions, be reconfigurable and extensible in the field and are made to be useful for the actual intended purpose and not playing. For now, I selected a simple name "​NatWatch"​ for the platform. This is an attempt to specify an extensible platform in the hope that it will be useful.
