Energy Efficient and Safe Weighted Clustering Algorithm for Mobile Wireless Sensor Networks

Algorithm 2

Algorithm reaffiliation phase.

Inputs:   ,;

Outputs: set of clusters

Begin

(1)  For num_cl = 1 to Count (Cluster) Do

(2)  If (Size (Cluster [num_cl]) < )

     Then

(3)   CH sends a message “RE_AFF_CH” to its neighbors

    ();

(4)    = Count ();

    EndIf

(5)  For   to   Do

(6)  If ( receives the message)

    && (Size (Cluster [num_cl]) < )

     Then

(7)    sends a Select message “REQ_RE_AFF” to the CH;

(8)  If (Size (Cluster [num_cl]) < )

     Then

(9)   CH sends a message “ACCEPT_RE_AFF” to ;

(10)   CH updates its state vector;

(11)   CH → CH → Size = Size + 1;

(12)    updates its state vector;

(13)    → CH → ID = ID;

(14)   Else CH sends a “FIN_AFF” message to ;

(15)   Go to (2);

    EndIF

(16)   Else   sends a “DROP_AFF” message to CH;

   EndIf

   End For
