The Anonymization Protection Algorithm Based on Fuzzy Clustering for the Ego of Data in the Internet of Things

Algorithm 1

Node clustering.

 Input: Spactab and ;

 Output: Subndgrp; % clustered node set

 BEGIN

 (1) Subndgrp =

 (2) FOR each in

 (3) ; % Value from is assigned to variable

 (4)   IF then

 (5)   Subndgrp = Subndgrp

 % Subndgrp is a node set which spatial adjacent degree is . represents

the subset of nodes, where, denotes the node number of the subset of spatial

adjacent nodes determined by . The number of nodes in each cluster subset is equal or

unequal. is shown as the mth subset determined by the

intercept . denotes the union of all sub sets.

NUMGRP represents the subset number determined by . %
