we have discussed HCTA based tracking and single hop routing and LEACH based

tracking and clustering routing. LEACH based tracking is divides sensor nodes in cluster. In each

cluster CH (cluster head) applies aggregation process on packets then directly transmits to sink node.

Thus, minimum packets transmit and packets does not route entire sensor nodes in WSN. CHs in

clusters transmit packets based on carrier sense multiple access collision avoidance (CSMA/CA), to prevent collision and minimize transmission and reception process. Overall energy conserve by LEACH during simulation is same.
