WSN(Wireless Sensor Network) is an emerging field that operates on real time datasets to detect any abnormality through classification modeling. Sensor is an integrated component of WSN that is used to collect data and then store within data store. Sensors have limited energy associated with them. Conserving energy so that data collection can be prolonged is discussed through this paper. There are number of mechanisms including LEACH, DEEC, MDEEC, EDEEC etc. all these mechanisms conserve energy but optimization in each protocol is missing. Problems associated with listed protocols are discussed and mechanisms used to overcome the problems are also briefed. Comparative analysis suggests. Nodes collaborating together form clusters. Data transmission takes place from distinct clusters towards base station. Energy of sensors needs to be preserved in order to enhance lifetime of network. This paper presents the overview of various existing techniques used to enhance lifetime of network. The degradation indicated in terms of packet drop ratio for determining network bandwidth. The analysis of some popular protocols has been done in this paper which can be can be used for future enhancements. DEEC protocol is best among all and can be used for optimization purpose. Energy efficiency predictions will be better in case sensors can consume less energy.
