Low-Energy Adaptive Clustering Hierarchy for Wireless Sensor Network: Protocol - LEACH

In this paper we are using a new technique LEACH for wireless sensor network. Sensor; is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. This paper presents an energy-efficient communication protocol which distributes a uniform energy load to the sensors in a wireless micro sensor network. In this paper, they present Event-to-Sink Directed Clustering (ESDC) protocol that achieves energy-efficient clustering in WSN. In this paper we are going to use clustering in homogeneous nodes in WSN. In addition to collect data from non cluster nodes the cluster head will aggregate the data which is to be transmitted to base station here we will use multi hop routing technique to transmit data to the base station .In addition to just use shortest path (Energy Conserved) we will also prefer to transmit data through the other nodes which have high energy difference as compared to the nodes which is transmitting data to base station.
