Enhanced modified LEACH (EMODLEACH) protocol for WSN

In LEACH, the minimum amplification energy required for inter cluster or Cluster head to Base station communication and amplification energy required for cluster members to cluster head transmission is identical. As a result packet drop ratio increases. The collisions or interference for other signals also increases. LEACH chosen its cluster heads periodically and distributes energy consumed uniformly by rotation. If we apply heterogeneity in this protocol it gives poor performance and less efficiency. To get an another chance to became a Cluster Head (CH) for next 1/p rounds is very difficult once a CH is formed. For every round, cluster heads are replaced and whole design of the protocol is changed. Basing on the mode of functioning, WSNs can be classified into proactive, reactive and hybrid networks. Reactive networks, respond immediately basing on the decision parameters. Our proposed protocol Enhanced Modified LEACH (EMODLEACH) is a reactive protocol which is implemented in homogeneous network model. We have implemented the concept of Efficient Cluster head Replacement scheme (ECHR)and Dual transmitting power level (DTP) of MODLEACH along with the concept of Efficient Intra Cluster transmission Scheme of TEEN.
