Abstract:
In this paper we introduce enhanced LEACH protocol based on low-power adaptive cluster
hierarchy in order to make the network energy consumption efficient and extend the life time
of nodes in the network. We use the modified threshold function to select the cluster head node,
by taking residual energy and node distance as a parameter. The center of gravity node is also
presented to help cluster head to finish its transmission and increasing the service duration.
In the multihop communication between clusters, in order to calculate the fitting factor of the
next hop, we derived a new formula, which takes into account the angle, remaining energy,
and distance. According to simulation data the total residual energy of the Enhanced LEACH
protocol is decreased, while the network life time is increased
