Software

Wiplan Software

Wiplan is an INSA Lyon registered software including an Indoor propagation engine and a wireless LAN optimization suite. The heart of this software is the propagation simulation core relying on the MR-FDPF (Multi-Resolution Frequency Domain Parflow) method, originally proposed by the CITI team. This method exploits the time-frequency duality to resolve the propagation problem as a large linear system. The key contribution relies on the multi-resolution approach that has been thought about. For the last few years, extensive works have been done to make predictions more realistic. This propagation comes with a network planning and optimization suite relying on a Tabu solver dedicated to multi-objective optimization.

WSim Software

WSim is a full platform hardware simulator targeting deeply embedded systems such as sensor network nodes and ambient devices. WSim offers high level debugging facilities as well as high level performance profi les. Time and energy simulation accuracy have been validated with real-world systems down to the clock cycle level.

WSNet Software

WSNet is a modular event-driven wireless network simulator offering a very precise physical layer with Rayleigh fading, multiple radio resources (codes, frequencies), correlation factors between different radio frequencies and radio codes, additive interferences, complex radio modulations, complex antenna radiation patterns. WSim can be used in conjunction with WSNet to simulate a whole sensor network with a very high accuracy. Both WSim and WSNet are registered at the APP.

Ambient OSGi

We have defined a framework and developed a programming environment relying on a standard Java/OSGi stack dedicated to ambient devices. This framework manage resource constrained devices using a minimal bootstrap environment that runs a standard Java/OSGi stack and loads the necessary missing classes from remote servers in memory at run-time. Already developed management tools are currently being integrated in this environment: tinyShell for a lightweight management user interface, JMX services package dedicated to standard MBeans, P2P services deployment, services execution isolation.

FISCO

FISCO is one of the first fully integrated schemes of self-configuration and self organization for Wireless Sensor Networks. The protocol can better resolve the distributed address allocation using the structure generated by itself with low message overhead, providing signifi cant energy savings. The implantation have been done on top of TinyOS environment and experimented on various hardware platforms. FISCO is able to manage efficiency gradientlike routing protocol, sink mobility, and perform data-aggregation.

FISCO implementation was done in collaboration with France Telecom R&D and is the property of the company.
