Energy efficiency is an important demand of Wireless Sensor Networks (WSNs). Through data aggregation, energy efficiency will be improved by filtering wrong information and merge redundant ones. If invalid transmitting is cut down, the nodes’ energy will be consumed and the utilization of wireless channel will be increased. Designing data aggregation algorithm is one of the most efficient research fields to improve WSNs’ performance. In Wireless Sensor Networks (WSNs), energy efficiency is one of the most important factors to improve the networks’ performance, and well designed routing algorithm can obviously modify the WSNs’ energy efficiency. In this paper, some existing work of different authors are analyzed, and the advantages and defects of these works are introduced.
