The Interplanetary Overlay...
A Linux port of the OpenBSD/FreeBSD Cryptographic Framework (OCF). This port aims to bring full asynchronous HW/SW crypto acceleration to the Linux kernel, OpenSwan, OpenSSL and applications using DES, 3DES, AES, MD5, SHA, PublicKey, RNGs and more.
PVNet is a project providing a virtual network interface. It generates numbers of pure virtual ethernet adapter. It is tested for Linux kernel 3.0.8 on amd64 cpu. Its code contains a kernel patch and module code. You can use it to create many ethernet cards. Each device has a single mac address.
OpenDMTP is a protocol/framework that allows communications with small devices (mobile phones, PDA's, and other high-latency/low-bandwidth devices), especially geared towards the transmission of GPS, temperature, and other remote monitoring information.
Simple Lossless Ad-hoc Protocol (SLAP) is designed to be used for wireless digital data transfer on embedded systems. The program is built for uClinux, a derivative of Linux designed for embedded microcontrollers, but can be easily ported.
Titan allows service-oriented processing of context recognition applications on Wireless Sensor Networks. It includes an execution environment developed for TinyOS and a Java ME (Personal Profile) Network Manager intended to be run on a mobile phone.
Small but complete enviroment for building custom embedded system (x86 and other). Based on the gentoo system and uclibc-embedded project. Ideal for small hardware like WRAP or Soekris.
A replacement firmware distribution for the 3com 3CRADSL72 a.k.a 3com wireless 11g (distributed by Ya.com) and its identical twin, the SMC7804WBRA, with an ucLinux kernel based system and associated system tools.
