The Internet of Things is used in both households and\r\nindustry to perform various tasks and increase business efficiency. However,\r\nwith widespread use, many questions have been raised about the security and\r\nscalability of IoT devices within the current architectural model. Before IoT can\r\nbe more widely deployed in everyday life and in critical infrastructure, its\r\nweaknesses must be addressed as effectively as possible. One way to address\r\nthese weaknesses is to use blockchain technology as part of IoT ecosystems. The\r\naim of this thesis is to investigate how the migration of IoT and blockchain\r\ntechnology takes place using different models and what positive effects it has.\r\nIn addition, the thesis takes a position on known problems. This thesis was carried\r\nout as a literature review. The study also found out what positive effects\r\nthe use of blockchains has on the operation of IoT devices in different environments.\r\nIn addition, potential problems that may arise as a result of the combination\r\nof technologies were identified. The study found that successful migration\r\nof blockchains and IoT-devices provides a significant advantage over the old\r\ncentralized architecture. Key benefits include the stability and data retention\r\nprovided by a decentralized architecture. In particular, the role of blockchains\r\nand IoT ecosystems as part of industrial development is largely covered in the\r\ndissertation. However, the dissertation also reveals many possible problem areas\r\nboth in the technical implementation and in the prevailing environment.\r\nProblems are caused by for example legislation and the current performance of\r\nIoT devices.\r\nKeywords: IoT, blockchain, Internet of Things, Decentralization", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2020-06-16T12:19:46Z\r\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-06-16T12:19:46Z (GMT).
