'''Low Energy Adaptive Clustering Hierarchy ("LEACH")'''<ref>Heinzelman, W., Chandrakasan, A., and Balakrishnan, H., "Energy-Efficient Communication Protocols for Wireless Microsensor Networks", Proceedings of the 33rd Hawaaian International Conference on Systems Science (HICSS), January 2000. [http://pdos.csail.mit.edu/decouto/papers/heinzelman00.pdf Paper]</ref> is a [[Time division multiple access|TDMA]]-based [[Media access control|MAC]] protocol which is integrated with clustering and a simple routing protocol in [[wireless sensor network]]s (WSNs)[https://www.researchgate.net/profile/Morteza_Mohammadi_Zanjireh/publication/257373717_ANCH_A_New_Clustering_Algorithm_for_Wireless_Sensor_Networks/links/0c960529efd0d2dbed000000.pdf]. The goal of LEACH is to lower the energy consumption required to create and maintain clusters in order to improve the life time of a wireless sensor network.
