As Wireless Sensor Networks (WSN) has become a rapidly growing field of interest, it is essential to know the various aspects, functionalities and the methodologies involved in this field. Data gathering in WSN involves collection of data from widely distributed set of sensor nodes. There are different algorithms to gather data in WSN based on the nature of the network topology and the nodes involved. Though there are many different techniques to achieve data gathering, not all of them provide optimized result. Also, in data gathering it is important to recognize a scheme that will ensure fairness in the data gathered. This paper provides a detailed understanding to the various data gathering methodologies for mobile sinks in WSNs.
