Node’s energy consumption is mainly divided into two
parts, signal transceiver (communication) and signal
processing. Studies[13-14] have shown that energy consumption
of communication is far greater than the signal processing,so
we only consider energy consumption of data transceiver,
assuming the size of data obtained by common node is l,the
proportion of clusters in kr is qr,qr>0(r is 1,2,…n),average
communication distance between common node and cluster
head in a cluster is 0 d .
