No.8（2013）2.Multi layer control applied middle-routing node in wireless sensor network

Yoshitsugu Nakagawa, Yasuharu Irizuki, Takashi Yamaguchi

  Today, monitoring using wireless sensor networks is being utilized in many fields including environment, welfare and agriculture. In particular, wide spread coverage of sensing of outside regions is known to cause operational problems such as cost and traffic reliability when transmitting information from a density covered region. Clustering is an efficient method to collect data and many such studies have been carried out. In this study, we construct representative nodes in a small range clustered subnetwork that can transmit interactively with a nucleus network. We focus on the middle-routing nodes which bridges between two different layers of the network. The middle-routing nodes both collect data in the cluster and transmit the data between clusters which efficiently transmit the data across the whole wide region of a network outside.
