TakaTuka is a Java virtual machine (JVM) mainly focused on wireless sensor network devices. The VM focussed on supporting small devices with at least 4 KiB of RAM and greater than 48 KiB of flash memory. TakaTuka currently offers CLDC compatible library support. TakaTuka was developed by University of Freiburg and first went public on SourceForge in 2009. It was created to reduce the learning time of developing wireless sensor network applications by introducing a common Java language among all supported mote.
