Energy Efficient Cluster based Reactive Algorithm in Wireless Sensor Networks


Objectives: To eliminate hot spot problem and achieve uniform load distribution among many cluster heads (CHs), we propose a cluster based reactive (CBR) algorithm with threshold based data transmission. Methods/Statistical Analysis: This study achieves innovation through the incorporation to two phases namely cluster head selection using the vote-based measure as well as transmission power of sensor nodes and reactive data transmission. In reactive data transmission, the sensor node sends data only while the sensed value exceeds the threshold value. Findings: A series of experiments are carried out to validate the goodness of the CBR algorithm in terms of energy utilization and network lifetime. From the experimental results, it is absolute that network lifetime of the proposed method is increased by 55.72% and the energy consumption is reduced to 50% when compared to LEACH. Application/Improvements: The proposed method can be implemented in real time WSN.
