ENERGY EFFICIENT CHARGING TECHNIQUE USING RADIO FREQUENCY (RF) FOR WIRELESS SENSING NODES IN UNTIDY AREAS

Abstract

Wireless Sensor Networks (WSNs) are widely used in various areas, including medical, battlefield, agricultural, industrial, and defence automation. In recent decades, numerous research studies have been conducted successfully in this area. However, after a thorough study of the recent work, it is concluded to more improve the power feeding and accuracy of the constraint nodes. This research focuses on the power consumption of sensor nodes, aiming to prolong their lifespan, especially in challenging environments such as untidy areas, mountains, hills, or underwater scenarios. In such an environment, the sensing capabilities of sensor nodes become weak and ultimately increases the data lost due to the non-availability of continued energy/power sources. This work aims to propose the technique to raise the ability of power consumption, the operational lifespan of each sensor, and the efficient selection of cluster heads. It fully concentrated on the signal of Radio Frequency which is transmitted by the RF transmitter and performs modulation on power consumption to enhance the variable energy for sensor nodes ultimately. Also, with the optimal cluster heads, the data is routed towards Base Station. RFHC (Radio Frequency based on harvesting cluster head) protocol is being proposed with a simulation scenario, compared with other standard solutions in terms of varying nodes. Simulation results show that RFHC improves overall performance by 25.3% over LEACH, 78% over LEACH-C, and 78.5% over Stat-Clus.
