On this basis of some inadequacies analysis for a classical LEACH protocol
such as the uneven distribution of cluster nodes caused by randomly selected cluster head
the cluster head selecting without considering the residual energy of the node and the single hop communication from cluster head to sink node
this paper presents the EB-LEACH protocol which was presented based on energy balance optimization.Therefore in the improved protocol
a class of relay nodes was added into WSN
and these relay nodes shared the work of forwarding data originally belonging to the cluster head
thence reduced the energy consumption of cluster head and made the energy consumption of node more even
which extended the life time of the entire sensor network.Then NS2 simulation tool was adapted to the simulation work of the improved protocol EB-LEACH and the original protocol LEACH.Study results show that the improved protocol in life time of the network
base station receiving data and energy consumption has better performance than the original protocol.
