Abstract: Wireless sensor network consists of thousands of tiny nodes. The nodes in network are directly connected. Routing protocols are used to discovering and maintaining route in network. There are mainly three types of routing protocols i.e. proactive, reactive and hybrid. They are further classified in flat based, hierarchical based and location based routing protocols. In this paper we discuss location based routing protocols. Here we briefly discuss existing routing protocols their advantages and disadvantages and also open research issue on them.
