Collaborative wireless sensor networks: A survey

This paper presents a review of the recent developments of collaborative wireless sensor networks (CWSN). CWSN focuses on collaboration in wireless sensor networks (WSN). It has applied on almost every research field of wireless sensor networks, such as localization, topology, protocol, environment sensing and coverage, energy aware, security, and so on. As the resource on each node is limited and there are lots of nodes in WSN, now it is becoming a significant and basic method of WSN, especially when there are bottlenecks that affect the performance of a node or the networks. This paper presents and discusses the concept and features of CWSN, its research trends and its applications, along with our recent researches. The relationship between CWSN and IOT (Internet of things)/CPS (Cyber physical systems) is also briefly discussed.
