Discrete Integrity Assuring Slice-Based Secured Data Aggregation Scheme for Wireless Sensor Network (DIA-SSDAS)

Table 4

Communication cost based on hops.

	Number of hops
Schemes without aggregation		is the number of layers and refers to the number of nodes at layer .
Ring topology with slicing		is the number of layers, refers to the number of nodes at layer , and “” refers to the number data slices generated per node.
Cluster topology		is the number of clusters and refers to the number of nodes at cluster .
Hierarchical cluster topology		is the number of clusters and refers to the number of nodes at cluster . is the number of clusters at level .
