Cluster Head Selection in a Homogeneous Wireless Sensor Network Ensuring Full Connectivity with Minimum Isolated Nodes

Algorithm 2

Function[Left_Neighbours] = notflag_neighbours(Neighbours, Setflag)

for i = 0 to Neighbours

{

   Min_count = min_setflag_count()

   node   is the CH

   set flag for   in the set Neighbours()

   set CH id’s   for in the set Neighbours()

   notflag_neighbours(Neighbours, Setflag)

    set Neighbours  =  left_neighbours

}

min_setflag_count is a function which calculates the minimum of of all the nodes in for which the flag is not set.
