Description: This paper studies LEACH protocol, and puts
forward energy-LEACH and multihop-LEACH
protocols. Energy-LEACH protocol improves the
choice method of the cluster head, makes some nodes
which have more residual energy as cluster heads in
next round. Multihop-LEACH protocol improves
communication mode from single hop to multi-hop
between cluster head and sink. Simulation results show
that energy-LEACH and multihop-LEACH protocols
have better performance than LEACH protocols.
