Background:
Wireless Sensor Network (WSN) is an arising field for research and development. It has various
applications ranging from environmental monitoring to battlefield surveillance and more. WSN is a collection of multiple
sensor nodes used for sensing the environment. But these sensing nodes are deployed in such areas where it is not that
easy to reach, so battery used in these nodes becomes quite impossible to change, so we need to utilize this energy to get
the maximum sensing for a long time.
Objective:
To use the Fuzzy approach in the clustering algorithm. Clustering is a key approach to prolong the network
lifetime with minimum energy utilization. In this paper, our main concern is on the Cluster Head (CH) selection. So, we
are proposing a clustering algorithm which is based on some of the attributes: Average Residual Energy of CHs, Average
Distance from nodes to CHs, Standard Deviation of member nodes, and Average Distance from CH to Base Station(BS).
Methods:
Initially, some of the nodes are found having greater residual energy than the average network energy, and
fifteen populations are made each having an optimum number of CHs. The final and best CHs set is chosen by
determining the maximum fitness value using a fuzzy approach.
Result:
The result positively supports the energy-efficient utilization with lifetime maximization, which is compared with
the Base algorithm [1] and LEACH [2] protocol based on residual energy and the number of nodes that die after
performing some rounds.
Conclusion:
The proposed algorithm determines a fuzzy-based fitness value, provides load-balancing among all the
networking nodes, and performs a selection of best Cluster Heads, resulting in prolonged network lifetime and maximized
efficiency.
