Recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor networks. The manufacturing of small and low-cost sensors has become technically and economically feasible. Wireless sensor network is a collection of some smart sensor nodes which collaborate among themselves to form a sensing network. Smart sensors are wireless computing devices that sense information in variety of environments to provide a multidimensional view of the environment. This paper briefly explains the routing protocols involved in wireless sensor networks, its classification and comparison.
