What is Self-Organisation

Recent application development in the wireless sensor networks (WSNs) area makes arise problems regarding data aggregation and effective methods to collect data. For addressing these problems, effective procedures are required. A multi-sink sensor network application has been characterized by many-to-many communication, where multiple sources report their data to multiple sinks. This article presents recent techniques for distributed multi-sink environments. The reviewed proposals are classified according to the purpose of the application, such as routing, monitoring of a specific target, data aggregation applications, and others. Finally, we present a discussion on the analysed works.
