The optimum use of energy in wireless sensor networks (WSNs) is
very important. The recent researches show that organising the network nodes
in some clusters leads to higher efficiency of energy and finally it increases the
lifetime of the network. So, controlling the number and the location of the
clusters head (CHs) and also the size of the clusters about the node number
leads to a balance in energy use of the CHs and increasing the lifetime of the
network. Clustering-based routing protocols are energy-efficient protocols that
improve the lifetime of a wireless sensor network. The objective of the
clustering is to minimise the total transmission power by aggregating into a
single path for prolonging the network lifetime. In this paper, fuzzy C-means
(FCM) algorithm is used for the optimum number of the CHs and their
location. Using FCM in WSNs helps changing the LEACH protocol parameters
while execution. The results show that the hybrid algorithm increases the
lifetime of the network in comparison to the LEACH algorithm.
