Abstract: Wireless Sensor Networks consist of small nodes with sensing and computation, communication capabilities. Wireless network are highly dependent on specific application and are constrained by energy, storage capacity and power. To increase the lifetime of networks, energy awareness is essential consideration if we analyze routing protocols. Routing protocols of sensor networks are responsible for maintaining the routs in the network. In this paper, we analyze recent routing protocols for wireless sensor network and classify in three types of approaches according to network architecture in WSN.The three main categories on the basis of network structure: Flat, Hierarchical and location based routing protocols. We study tradeoff between energy and communication overhead savings in every routing prortcols.We also highlighted the advantages and performance issues of each routing technique
