As we know wireless sensor network have many advantages such as its high speed and high quality which increase its use in modern time. As so the security in wireless sensor network became the most important factor. There are many security issues but the most important is “eavesdropping”. Eavesdropping is a type of attack in which the information being transmitted is attained or captured by some other devices. It is not possible to tell if a system had faced some kind of eavesdropping or not. In this paper various advantages and disadvantages will be discussed. There will be some application of WSNS and some introduction of eavesdropping issue with some techniques to detect this issue. We will also see various other attacks which leads to effect the security of wireless sensor networks. This paper will help in improving security in wireless sensor networks. This paper will further help in improving accuracy of wireless sensor networks. This paper will also light up various advantages and disadvantage of the technique which is being used for improving the security of wireless sensor networks.
