Wireless sensor network applications are becoming the main concern of several studies. Not only they allow to maintain more varied measures in several fields notably that of real time hydraulic systems control and surveillance. But their dense deployment decreases granularity which can lead to the comprehension of some unexplainable phenomena. However, the effectiveness of a sensor network not only depends on the quality of the sensors individually, but also on their collaboration. The latter is only possible with reliable routing protocols which have to adjust to fit the constraints imposed by the application. With this aim in mind, we suggest in the current work a new extension of SCTP (Stream Control Transmission Protocol) that we call SCTP-WSN (wireless sensor network). This extension will have as a main function to improve the communicative performances of sparse wireless sensor networks with dynamic topologies. In order to do this, this extension will have to improve the availability of the links in sparse sensor networks by a better integration of the Multihoming concept, representing therefore a more reliable data collection subsystem for a real time detection of possible disorders affecting drinking water supply systems.
