Theoretical background

 Overview

This section enables the readers to acquire an in-depth theoretical knowledge on the topics that are related to research. Further this chapter is sub classified into four sections where the first section gives a brief idea on purpose of considering data aggregation in WSN.The second section discusses about data aggregation in WSN and further explains how the process of data aggregation carries out in WSN. Third section explains comparison of WSN with and without data aggregation and fourth section clearly illustrates data gathering transmission. Finally it summarizes the chapter.

Purpose of Data Aggregation in WSN

In current scenariosthe demand for WSN had rapidly increased in various applications like weather monitoring, petroleum and military due to low power, small size, light weight, and wireless sensors. However these inexpensive sensors are equippedwith limited battery power and thus constrained in energy [10]. One of the major issueswith WSN is that one need to increase the lifetime of network. Generally,lifetime of network is defined as the time whenever the first node fails to send its information to base station. This issue can be resolved by implementing data aggregation technique as it decreases data traffic and further saves energy by merging multiple incoming packets into a single packetwhenever the sensed information are highly correlated [66].Numerous researches have been carried out to further extent
network lifetime.

Data Aggregation in Wireless Sensor

Networks It is just a process of aggregating the sensor information through aggregation approaches. This technique was mainly utilized to resolve both overlap and implosion problem in data centric routing [22]. In data aggregation the sensor network is generally supposed as reverse multicast tree. Here, sink request the sensor nodes to report ambient condition of phenomena. In this process, generally the information that is coming from several sensor nodes are aggregated in such a way that they are about same attribute of phenomenon once it reach the same routing node on way back to sink.

Data Aggregation Techniques

Generally the data aggregation can be classified on basis of network topology, quality of services, network basis and many more. For the current research, the techniques are being discussed based on the network topology. In this topology, the data aggregation technique is categorized into two parts which are flat and hierarchical network.Further hierarchical network is sub-classified into four parts which are cluster based,chain based, tree based and grid based.
