Energy efficient Wireless Sensor Networks using FAF and dual cluster head technique for weed detection

The main challenge of Wireless Sensor Networks is to transfer the data with less cost and energy. Another requirement of efficient WSN is to have a maximum lifetime of sensor nodes. This lifetime of sensor nodes gets reduced due to usage of large amounts of energy and fading. To overcome this barrier, many techniques such as, LEACH, PEGASIS etc., are invented over the decades. Existing system used single cluster head to transfer the data from nodes to base station. This paper proposes the concept of dual cluster head which follows sleep and awake modes to share the work load. AODV routing protocol is used in this technique. Here the next hop is selected based on forward aware factor (FAF). This system improved the energy efficiency and reduced the delay. Experimental results are compared with LEACH and PEGASIS. It has been proved that this system outstripped the other traditional systems. This technique can be used for weed detection among cereal crops.
