Resource-constrained is a critical issue in Wireless Sensor Networks (WSNs) applications. Data aggregation is an efficient method to conserve energy by reducing packet transmissions and extend the network lifetime in WSNs. The total lifetime of the network is a major design factor for protocols used by WSNs. Routing protocols with low energy consumption are needed to prolong the lifetime of sensor network. In this paper, data aggregation based routing protocols for WSNs are analyzed. The routing protocols of structured architecture such as tree-based, cluster-based, chain-based and unstructured architecture such as structure-free are reviewed. The directions for future research are proposed in this area.
