The quick growth in network multimedia equipments have allow additional real-time digital services such as video-conferencing, online games and distance education to develop to be the standard internet tasks. WSNs is now major part of research in computational theory because wide variety of applications. But due to limited battery power consumption has become major limitations of WSNs protocols. Though many protocols has been proposed so far to improve the energy efficiency further but still much enhancement can be done. This paper has presented various data aggregation techniques for WSNs.
