Wireless Sensor Network (WSN) consists of distributed self-governing sensors to monitor physical or environmental conditions. WSN consist of an collection of sensor. The area of wireless sensor network is one of the emerging and fast growing field in the world but there are some key issues in WSN such as maximizing the network lifetime. Network lifetime is important in sensor node when the sensor node, distributed typically in remote area is powered by finite energy batteries. Likewise many more issues and problems in WSN are going to be discussed in this paper.
