Performance Evaluation of Modified LEACH Protocol in WSN

Abstract

Wireless technology has expanded the limits of our world, It used to offer a powerful combination of distributed sensing, computing, communication and also to enable better data collection in scientific studies, it used in countless application, the major challenges in design of wireless sensor networks (WSNs) is to minimize power dissipation so routing protocols are used to reduce power consumption, clustering plays an important role for energy saving and also helps in achieving efficient and scalable control, in an efficient clustering approach, radio communication distance should be minimized. In applications based on large scale WSNs that requires scalability to hundreds or thousands of nodes, usage of hierarchical clustering will be extremely useful. Low- Energy Adaptive Clustering Hierarchical (LEACH) is parent of hierarchical clustering routing protocol is considered and improved. We propose a clustering routing protocol named Enhanced MOD LEACH is evaluated which extend MOD LEACH protocol by balancing the energy consumption in the network, simulation studies were done to evaluate the performance of the proposed model.
