The resource limitations of wireless sensor nodes foster the collaborative nature of wireless sensor networks (WSNs). Thus, in this paper, we propose a generic model that represents the collaboration relationships that can be established in a WSN, and its implementation. To accomplish this, we approach the different types of collaboration that may occur in any WSN. As a result, we propose a collaboration hierarchy for WSNs. Furthermore, we present the WISE-MANager tool, which is a collaborative sessions' management tool that allows bringing these concepts into practice. The establishment of collaborative sessions, using a test-bed composed by ZigBee-based sensor nodes allows demonstrating that the WISE-MANager tool optimises the WSN's operation and increases the interaction between the user and the network.
