Commonly monitored parameters are humidity, temperature, air pressure, wind speed and direction, sunlight, volume intensity, vibration intensity, illumination intensity, pollution levels and Human Emotions etc. This paper provides the general idea of WSN, Unique features of WSN, WSN Node Architecture and Routing protocols of Sensor Network. Keywords: Wireless Sensor Network, Topology , MANET, Routing Protocols I. Introduction To Wireless Sensor Networks:- A sensor network consists of sensor nodes which work as multiple detection stations. Each node is tiny, frivolous and movable unit. Every sensor node is consist of a microcomputer, transceiver, transducer and power source. The physical effects get sensed and electrical signals get generated by transducer. Generated sensor output get stored by microcomputer processes. Generally hard-wired or some wireless devices are worked as transceiver and transmits data to other computer system. Battery or electric service derives power for each sensor. Applications of sensor networks include:  In Business  In Class Room  For Safety and Security i.e. video inspection  For Environment i.e. monitoring and sensing of climate conditions  In Medical Field, for monitoring of medical devices  In automation of Industrial tools  Automated and smart homes  In Traffic monitoring  In Robotics  In Aeronautical Science II. Inimitable Features Of Sensor Networks:- It is obvious that ad hoc network and sensor network have some common things to share. Hence, protocols designed for sensor networks must comprise for the properties of wireless (ad-hoc) networks, including the subsequent properties. 1. Untrustworthy data transmission because of wireless network. 2. Though WSN having lot of unique features which are not present in existing ad-hoc networks, there is need of self configuration of nodes which requires slight human involvement. 3. As network consists of nodes and nodes get charged by either electrical supply or batteries, hence every node is having limited life. 4. Number of nodes in WSN is more than traditional ad-hoc networks. 5. Traditional nodes provided mobility and hence every node is over weighted, but sensor nodes are usually motionless. 6. Due to harsh environment, node failure is common. 7. As node size of sensor network is small they are facing challenges like short lifetime, less memory and calculation power. 8. Wireless sensor network requires location info. 9. Sensor networks are more cooperative than traditional wireless network as sensor networks try to achieve similar worldwide aim which helps to maintain quality of service. 10. As sensor network uses M-to-1 traffic, “Wi-Fi” problems may occur. 11. Packets are used to move the data and hence layer wise overhead get increased. Including these exclusive features, Sensor network capably make use of bounded resources of network. This escorts to quite different protocols for different layers of network, each with
