摘要：A Wireless Sensor Network (WSN) is built from a network of devices referred to as nodes, which cansense the environment and are used to communicate the required information collected from monitored fields. Thecommunication and collection of information is done with the help of wireless links, where each node is linked to oneor a number of sensors. The nodes in turn are deployed in large numbers depending upon the application where it isused. In modern days the process is bidirectional where the sensor activity can be monitored. The longevity in networklifetime is necessary as they have limited battery power which is to be used efficiently. This has led to new horizonsupon energy saving and reduced power consumption among sensor nodes. Hierarchical cluster-based routing protocolsare considered as one of the most efficient routing protocols in wireless sensor networks (WSN) due to its higherenergy efficiency, network scalability, and lower data retransmission. An energy efficient hierarchical routing protocolLEACH-EN based on LEACH-C is designed by introducing the concept of TDMA scheduling along with compressionof data from each node using LZW compression technique. The proposed LEACH-EN seems to perform well ascollision is avoided using TDMA and hence data can be transmitted faster.
