Wireless sensor networks (WSN) have a set of algorithms and protocols with self-establishing capabilities. These sensors work with each and every different to sense some bodily phenomenon after which the information gather is processed to get relevant outcomes. These sensor nodes can calculate, sense, and assemble particulars from the atmospheres and based totally on some nearby decision process, they are in a position to transmit the sensed files to the person. The battery is the foremost electrical energy grant in a sensor node and secondary energy supply that harvests energy from the atmospheres together with photo voltaic panels may additionally be brought to the node depending on the appropriateness of the atmospheres where the sensor will be diffuse. Clustering is the method which performs the grouping of similar nodes and then starts communicating into the clusters. Security can be finished by means of encrypting and decrypting the facts and make them unable to read that from the malicious users. Cryptography is the useful technique which contains symmetric and asymmetric methods. In this paper we find out about about WSN and its utility or a number of assaults which exist in the sensor community in the middle of paper we talk about a variety of existing technique and it�s working. Various assaults are carried out in this community such as passive and lively assaults or insider and outsider attacks. The wireless network always required protection in the form of information integrity, confidentiality, authenticity and etc.
