Security Issues in Blockchain Integrated WSN: Challenges and Concerns

In cutting edge era the foremost valuable information is ‘Data’, and WSN system has become one in all the integrated elements of our life. From smart phones to shrewd watches, there’s tons of data creation in each and every moment and wireless sensors are one of the primary components of WSN framework. Wireless sensors are utilized in all the WSN systems in corporated gadgets like advanced mobile phones, watches, fitness tracker and so on., these sensors are easy to use and have numerous distinctive characteristics. WSNs are used for real time trailing and surveillance purposes, where the nodes collaborate with each other to pass and retrieve the information. However, there are chances of compromise of data, so security turns into a major issue in WSN. Blockchain is a secure database i.e., a ledger that monitors all transactions occurring. In this paper, an in-depth survey on blockchain integrated WSN is done and the security parameters are also dealt thoroughly.
