Algorithm 3

Function of .

function struc_data = up_stuct_property(data)

% Utilized for updating the dead sink nodes

% Work out value for individuals, adjacency matrix, distance matrix, give back the structure struc_data

% clust_point: cluster individuals of per line

% num_categ: numbers of cluster

% A: initial data adjacency matrix

% D: initial data distance matrix

% data: structure of different categories

% cluster center

sum_D = sum((data.D)′);

[sum_sort_D, flag] = sort(sum_D); % distance arranged from small to lrge, the second small one as the center

data.center = data.point(flag(2)); % choose the second small one as the sink node center

struc_data = data
