Security issues in Wireless Sensor Networks What the security issues are related to Wireless Sensor Networks Name:Sandeep Kumar Pulijala Student ID:S0261345 Teacher:Erin Class:DEA3 Central Queensland University What the security issues are related to Wireless Sensor Networks Wireless sensor networks are very important in everyday life. This new technology is exciting with unlimited potential for numerous application areas including environmental, medical, military, transportation, entertainment, emergency management and homeland defence. WSN are connected with nodes, in WSN communication takes place through air. The exploration subject that I have picked is on Wireless…show more content…
An extension of this approach is in-network aggregation which aggregates data progressively as it is passed through a network. In-network data aggregation can reduce the data packet size, the number of data transmissions and the number of nodes involved in gathering data from a WSN. Therefore, in the field of WSNs, privacy-preserving data aggregation is becoming a hot issue in WSNs. To address this issue, some protocols have been proposed. In this, they provide a comprehensive summary and comparison of the existing privacy-preserving data aggregation protocols for WSNs. WSN is related to privacy-preserving data aggregation protocols (Ping et al 2012). In the authors reviewed privacy-preserving techniques for protecting two types of private information: data-oriented and context-oriented privacy. First, authors focuses only on data privacy in order to provide detailed overviews of the existing privacy-preserving data aggregation protocols for WSNs (Ping et al 2012). Two main security challenges in secure data aggregation are confidentiality and integrity of data (Sugandhi et al 2013). While traditionally encryption is used to provide end to end confidentiality in Wireless Sensor Network (WSN), the aggregators in a secure data aggregation scenario need to decrypt the encrypted data to perform aggregation. Thus, while data aggregation improves energy efficiency of a network, it complicates the existing
