Recent improvements in the field of micro-electro-mechanical system, digital electronics and wireless communication technology are responsible for the development in applications of wireless sensor networks. Wireless Sensor Networks (WSNs) are consisting of large number of cheap and tiny devices known as sensor nodes. In WSNs, sensor nodes communicate to each other via the many communication approaches and these routing approaches are governed by routing protocols. These routing protocols are reliable for performance of wireless sensor networks. On the basis of these, this paper contains the survey on wireless sensor networks.
