. This work explores the WSN architecture according to the OSI model with some protocols in order to achieve good background on the wireless sensor network. The wireless sensor network is a combination of sensing, computation, and communication into a single tiny device. A Wireless sensor network consists of an array of several sensor networks of different types interconnected by a wireless communication network. Sensor data is shared between these sensor nodes. The system extracts relevant information from the available data. It acts as information source, sensing and collecting data samples from the environment. Node can also act as information sink, receiving dynamic configuration information from other nodes or external entities. The end portion of a node can be an antenna. The WSNs need not communicate directly with the nearest high-power control tower or base station, but only with their local peers. The main objectives is to improve energy efficiency, network life time and to reduce delay time. These sensors are used to collect the information from the environment and pass it on to base station. A base station provides a connection to the wired world where the collected data is processed, analysed, and presented to useful applications. The cluster-based technique is one of the good approaches to reduce energy consumption in wireless sensor networks., Wireless Sensor Network can be used as a tool to bridge real and virtual environment.
