Wireless body area network has a strong correlation between applications
and different scenes have different demands for the network
so it is necessary to make pointed references to the network design.This paper sets up a LEACH algorithm model for WBAN based on the biological safety
after improving some of the drawbacks
such as cluster head marginalization
it considers the utilization rate of resources as well as the life cycle of the single nodes in the WBAN and important nodes in different scenes and then proposes a low energy-wireless body area network algorithm.The results of the NS2 simulation and analysis prove the LE-WBAN prolongs the life of single nodes and the network effectively
which conforms to the low power consumption and energy-efficient requirements of the WBAN.
