Network Lifetime Comparative Analysis in Wireless Sensor Networks

A Cluster-based Hierarchical routing is the classical methods in Wireless Sensor Networks (WSN) routing. Standard methods used are LEACH, EAMMH. The network life time of these algorithms has a significant improvement; if not major. By optimizing cluster head allocation and power levels of transmission power of a traditional LEACH algorithm, will have a significant improvement in lifetime of network comparatively. This algorithm here is referred as M-LEACH. Network Life time analysis has been made by comparing number of dead nodes after each node, that is, First node dead and Half nodes dead. Comparing these criteria with the three algorithms will give a understanding on a suitable algorithm for better network life time.
