Wireless Sensor Network (WSN) is latest technology for sensing and processing different physical and environmental condition data such as heat, temperature, pressure, etc. WSN is the network of small sensing node and these nodes have capability of sensing data and communicating with base station (sink node). WSN also have routing capability that route the data to sink node using various routing protocol. WSN routing protocol classified into various types based on network tropology i.e. flat, hierarchical and location based routing protocol in WSN used for selecting optimal routes path in sensor network.
