I. Introduction
Wireless sensor network well known topic in current time because it is use very casually nowadays. In wireless sensor network sensor node are connected through wireless medium and communicate the information to each other. WSN is a group of sensor node with at least one base station. Base station work as a gateway after that it is transfer the information to users using internet and many others ways. In wireless sensor network technology many small sensor node arrange in intense mode. They are communicating the same data type or collect same information not compulsory these are close to each and every node. Wireless sensor network operate on spatial distributed autonomous nodes, which is control the environmental and physical status that is temperature, vibration, motion, sound or pressure. Sensors nodes are affordable cost as well as small device, which is perform many operation. Every sensor node has some basic points such as processor, sensor, transmitter or receiver. These points divided into unit that is processing unit, sensing unit, transmission unit as well as power supply unit.
