Network Lifetime Improvement of Wireless Sensor Network using K-LEACH Protocol
Manisha N.Barsale, Radhika D. Joshi · 2022
Wireless Sensor Network comprises of sensor nodes that are energy constrained so Energy efficiency becomes a critical performance parameter in WSN. It is essential to improve Network Lifetime by means of extending node’s energy without affecting other network parameters. In order to make network energy efficient, various routing protocols are used in WSN. LEACH is one of the routing protocol that aims at reduced energy consumption. LEACH is a Hierarchical, most commonly used MAC layer protocol in WSN due to its simplicity and ability to handle large data sets. Energy conservation in LEACH can be enhanced by using k-means clustering algorithm which is based on machine learning technique. K-means clustering algorithm is used to select the most suitable Cluster head for energy optimization in the network. The proposed work is carried out on MATLAB. The combination of LEACH and k-means results into improved network lifetime and lesser energy consumption.
