A Comparative Study and Analysis of Data Aggregation Techniques in WSN

The comprehensive survey on various routing protocols supporting data-aggregation algorithms in WSN is studied. The main focus of all the existing algorithm is on optimizes them based on the vital parameter. It includes energy conservation, improving the network lifetime and reducing the data latency. In this paper, the key features with its merits and challenges of the various existing data aggregation algorithm are discussed briefly. It is evident from the simulation results that infrastructure of the network strongly influences the performance of data aggregation protocol.
