What is a sensor?
A sensor is a device which produces a measurable response to a
change in physical condition such as temperature or chemical
condition such as concentration.
What is a sensor network?
A sensor networkis composed of a large number of sensornodes, which are densely deployed either inside the phenomenon or
very close to it.

The node discards the packets having been seen
source
destination
The source broadcasts a route packet The neighbors in turn broadcast the packet till it reaches
the destination
Reply packet follows the reverse path of route request packet recorded in
broadcast packet

The studies and simulations show that the LEACH protocol
optimize energy consumption more than DD and AODV protocol.
This protocol allows us to space out the lifespan of the nodes, allowing
it to do only the minimum works it needs to transmit data. That how
LEACH is seen as the protocol who optimize energy in network.
