▲Shortcomings of LEACH include:
* Remaining energy among the nodes isn't considered when selecting Cluster Heads
Line 39 ⟶ 27:
* Random and uneven distribution of cluster heads
* Single hop communication in situations where energy use is less efficient from cluster head to base station
* Multi-clustering might not be required at some point and, at some point, number of optimum clusters could be as high as N (number of live nodes in the network)<ref>{{Cite journal |last1=Roy |first1=Nihar Ranjan |last2=Chandra |first2=Pravin |date=2018 |title=A Note on Optimum Cluster Estimation in LEACH Protocol |journal=IEEE Access |volume=6 |pages=65690–65696 |doi=10.1109/ACCESS.2018.2877704 |s2cid=53779139 |issn=2169-3536|doi-access=free |bibcode=2018IEEEA...665690R }}</ref>
