Communication has its roots right from the beginning of the human race. As humans evolved the need for communication increased tremendously and as well the technology of communication progressed. The era of communication from analog to digital has further advanced to wireless with Sensor networks occupying the most of area in communication nowadays. Communication community is highly depending upon wireless sensor networks and they are the key technology in communications. Even though these networks are widely used they are is still need for research such that its full features and the advantages can be fully utilized in the field of communication. The basic concern of these networks is energy and security as the energy is limited and the networks are wireless. Hence more algorithms have been developed for the energy efficiency. The popular among these networks is the Low Energy Adaptive Clustering Hierarchy (LEACH) algorithm. In this paper, a modification of MODLEACH with cluster based routing is developed as Modified LEACH(MODLEACH) in which the energy efficiency is increased considerably. The method of alternate cluster head is introduced by allotting threshold power levels. The results of this paper are studied along with LEACH and found to be appreciably good. The network metrics of cluster head formation, energy efficiency throughput and network life. An analysis is done with hard and soft threshold levels of the cluster head are studied.
