Energy Efficient Clustering Scheme to Improve the Lifespan of WSN

Wireless sensor networks (WSN) has been used in many areas like healthcare, defense, disaster, agriculture, etc. in the various application based on WSN have one BS and many numbers of the sensor device to monitor pressure-temperature in various environment condition. wsn consist of small tiny devices called sensor nodes (SNs) having few limitations in stipulations of sensing range and battery. There are numerous parameter plays an important role for designing an effective protocol of WSN to improve the lifespan of WSN. To minimize the energy dissipation of the SN and enhance the lifespan of the wireless sensor networks is a big issue. This article proposed a protocol to increase the lifespan of WSN using CH selection. The selection of CH is based on the distance to BS, residual energy, and node density. CH selection aims to reduce energy utilization and enhance the lifespan of WSN as compare to HEED and SEP protocol.
