Blockchain enabled trust management System for IOT edge networks

Abstract

The concept of things-to-things communication The internet of things newlinehas been introduced to fulfill the needs of the modern era. Smart cities, the newlineInternet of Medical Things, industrial IoT, Vehicular Networks, etc., are a few newlineexamples where IoT became the primary cause of origin. Such IoT networks newlinewere built with several network components. The sensors and gatherers were newlinethe finest and most economically good solutions for building the network. To newlineprocess the sensed and gathered data, a large-scale computation facility was newlinerequired. Deployment of such a big computation environment at all the newlinerequired locations was not economically feasible. Thus, cloud computation newlinehas been introduced. newlineCloud provided a large-scale computation facility by utilizing the newlineservers placed at remote locations. Many applications were developed on top newlineof cloud technology. Cloud computing was capable to serve almost all the newlineexisting requirements of IoT applications. But, the introduction of real-time newlineapplications to IoT-enabled environments demanded more efficient newlinecomputation facilities. The cloud technology was inefficient to serve the needs newlineof real-time applications due to the increased latency, expected link failures, newlinevii newlinelimitations of centralized computation, etc. The concept of serving the newlineconnected IoT devices from the edge of the network called Edge computing newlinehas been introduced to overcome the drawbacks of cloud servers. Edge servers newlinewere deployed near the IoT devices and the computation needs were served newlinedirectly by the edge servers. Edge servers only have limited computation newlinecapacity. Thus, a large-scale deployment of edge servers was needed to fulfill newlinethe needs of the advanced IoT environment. Edge servers could overcome the newlinethreats of single-point failure associated with centralized cloud servers. There newlineare several security limitations associated with edge server deployment. Now, newlinethe research in this area mainly focuses on securing the edge-enabled IoT newlineenvironment. newlineThe attackers utilize the vulnerabilities of the edge
