Multihopping Multilevel Clustering Heterogeneity-Sensitive Optimized Routing Protocol for Wireless Sensor Networks

Algorithm 1

Cluster-Heads selection by HCA.

Initialization;

Nodes define their type after random distribution and

compare their , coordinates with defined boundary by

radius of BS

Set of CHs denoted by which is empty at initialization;

while  Selection of NDL  do

if  nodes in distributed region  then

for  Calculate probability and threshold value

  do

;

if  threshold is greater than random number

then

tag is as a CH;

set = +1;

else

member node;

end

end

else

end

if  Nodes are in centralized region  then

for  Calculate ECR  do

;

if  Set of CHs are selected with most suitable

value  then

tag is as a CHs;

set = +1;

else

member node;
