Enhanced Energy Efficient LEACH Protocol Using Adaptive Filter in WSN

Wireless sensor network is most used network of today's world. Sensor node is the basic component of sensor network and having resources constrained like less memory, processing and battery power. These sensors are battery operated which means have limited battery capacity. It is important to efficiently use this battery so that network lifetime should be increased. Hierarchical routing protocols are energy efficient routing protocols which allows the sensor nodes to communicate with an energy efficient way. LEACH (Low Energy Adaptive Clustering hierarchical protocol) is clustering based hierarchical routing protocol which helps to reduce the power consumption by distributing the load among each sensor node and putting these sensor nodes into sleep mode when not in use. We use appropriate adaptive filter which is also energy efficient and helps to reduce the effect of noise and noise free data is received to sink. So, this leads to save the energy consumption and accurate data for making accurate decision by the base station for better utilization of the sensor network and fulfil the goal of implementation of the sensor network.
