How to extend the lifetime of the Wireless Sensor Network
is a hot issue to be researched since the sensor node’s
energy is limited.
LEACH is a famous clustering algorithm to
balance the node energy consumption in the Wireless Sensor Network. The
distributions of the energy consumption for various scenarios
in LEACH are analyzed in this paper.
And the main reasons
are found that leading to the asymmetry of the energy
consumption among nodes. According to the characteristics
of energy consumption, we presented an improved LEACH,
which can effectively balance each node’s load and improve
the network lifetime.
