Research of clustering protocol based on correlation of sensed data
Yingchun Zhou · Computer Engineering and Applications Journal · 2011
Considering the spatio-temporal correlation of sensed data,the clustering algorithm based on correlation of sensed data for wireless sensor network is proposed.According to the correlation of sensed data in CACD algorithm,sensor nodes with the same or similar data are divided into the same region.In cluster construction stage,the member nodes of a cluster come from the same region.There is only one cluster head communicating with base station in each region.In the intra-cluster communication,the continuously same data is transmitted only once.Because this algorithm takes account of reducing redundant data during transmission,it can prolong the lifetime of the whole network.
