Abstract: Wireless Sensor Networks (WSNs) plays a vital role in different structured applications such as health scrutinizing, ecological observing in industries, farms, colonized areas and so on. Wireless sensor networks (WSN) engage numerous sensor nodes for data transmission with inadequate power. Due to lower cost property of wireless sensors, the degree of usability is also large in vast applications. Sensor networks are group of sensor nodes which forward sensed data to base station responsively. As sensor nodes are supported by battery, a proper utilization of energy is crucial to use networks for prolong lifetime. Hence, the challenge lies in reduce the sensor network traffic, collision found inside the network, and reduce degree of data that need to send to base station. The main objective of data aggregation algorithms is to collect and aggregate data in a proficient way so that network lifetime is enhanced. Most preferred manner to extend lifetime, reduce time and cost during data transmission enhances the WSN. One such technique is data aggregation, a more interesting approach for data collecting in shared environment and active access through wireless connectivity.
