Performance Comparison in Terms of Communication Overhead for Wireless Sensor Network Based on Clustering Technique

Wireless sensor network refers to a group of spatially distributed and dedicated sensors for monitoring and recording the physical conditions of environment like temperature, sound, pollution levels, humidity, wind speed with direction and pressure. Sensors are self powered nodes which also possess limited processing capabilities and the nodes communicate wirelessly through a gateway. The capability of sensing, processing and communication found in sensor networks lead to a vast number of applications of wireless sensor networks in areas such as environmental monitoring, warfare, education, agriculture to name a few.
