Proposing the best cluster head selection technique so that life of each node may increase.

1. Study OnEnergy Efficient Centralized Routing Protocol For Wireless Sensor Networks Based on LEACH-C Supervised By TanayDey, Lecturer, Dept. of CSE, KUET, Bangladesh. Presented By Bijan Kumar Debroy(0507008) Md. Al-Imran(0507011) Dept. of CSE, KUET, Bangladesh.

2. Introduction Consists of hundreds or thousands of nodes Sense data, gather data and send to base station(BS) Various protocols are used. Such as- Direct Communication MTE LEACH: self elected cluster head LEACH-C: base station choose the cluster head BCDCP

3. Application 3

4. Routing Protocols Clustering protocols include- LEACH, LEACH-C etc. 4 WSNs Protocols based on

5. Motive of Clustering 5 Figure: Clustered Network

6. Problem Statement It consumes more energy MTE considers only energy of transmitter, neglects receiver In LEACH, energy consumption increases due to not equally divided In LEACH-C, extra GPS system is needed
