A Hierarchical Cooperation Model for Sensor Networks Supported Cooperative Work

Complicated multimedia sensor networks pose several theoretic and technical challenges. These challenges center on cooperative work supported by sensor networks. This paper presents, with the aid of previous works on CSCW, a novel conception—Sensor Networks Supported Cooperative Work (SNSCW). First, we classify the cooperative work supported by sensor networks into: cooperation between human and sensor nodes, and cooperation among sensor nodes. Then we depict the hierarchical collaboration by speech-action model and layered abstract model (activity-task-cooperation). Moreover, this paper proposes a multi-level C/S architecture for SNSCW system. Finally, we utilize a case-the fire monitoring of intelligent building-to show that our works are effective to cooperative work supported by sensor networks.
