DEAPspace-transient ad-hoc networking of pervasive devices

The DEAPspace project is building an interaction framework for connecting pervasive devices over the wireless medium, supporting the development of new proximity-based collective distributed applications. The main components of this framework are the discovery algorithm and the service description model. DEAPspace provides devices with useful information about the other devices in their surroundings. This information can be queried in a consistent way that will tolerate evolutions, and allow legacy devices to continue to function in the fast-developing world of pervasive gadgets. The discovery is done in a power-efficient, and network-friendly way, and will adapt to a wide range of error conditions. This framework has been implemented, and allows the development of distributed applications that use ad-hoc transient networking as part of their function. The primary implementation was in Java. A subset of the code was also written in C, to allow the use of machines which do not have a JVM. In addition to simulation, the code has been tested over TCP/IP and the Ethernet interface of an 802.11 link
