Wireless Sensor Networks (WSNs) have become a significant research challenge, attracting many researchers. This paper provides an overview of collaborative WSN, reviewing the algorithms, techniques and state-of-the-art developed so far. The authors discuss the research challenges and opportunities in this area. The major focus is given to cooperative signal and information processing in collaborative WSN in order to expose important constraints in wireless applications which require distributed computing, such as node localization, detection and tracking. In this paper, they also present and discuss the applications of multi-agent systems into WSN as a core technology of cooperative information processing.
