Wireless sensor network composed of infrastructureless, small, low-power, low cost, dynamic nature, application oriented, and multi-hoping wireless nodes, design for the purpose of collecting information by environment sensing, processing and communication. Designing of these networks become more complicated due to deploy nodes characteristics, maintenance of database, security, authentication and its functioning in open environment. This paper presents a general overview of WSN in detail and covers its applications and vulnerable aspects of WSN. Wireless Sensor Networks which is a type of wireless network consist of small distributed self-organized autonomous devices using sensors to cooperatively monitor physical or environmental conditions, (such as vibration, motion, temperature, sound, and Pressure) and send information wirelessly.
