Supple: a flexible probabilistic data dissemination protocol for wireless sensor networks

Participants : Aline Carneiro Viana, Thomas Hérault, Thomas LArgillier, Sylvain Peyronnet, Fatiha Zaidi.

We propose a flexible proactive data dissemination approach for data gathering in self-organized Wireless Sensor Networks (WSN). Our protocol Supple, effectively distributes and stores monitored data in WSNs such that it can be later sent to or retrieved by a sink. Supple empowers sensors with the ability to make on the fly forwarding and data storing decisions and relies on flexible and self-organizing selection criteria, which can follow any predefined distribution law. Using formal analysis and simulation, we show that Supple is effective in selecting storing nodes that respect the predefined distribution criterion with low overhead and limited network knowledge.
