Energy Efficient Qos Aware Decentralized Blockchain Framework for Fog Computing

Abstract

With the rush from cloud offerings and pull from IoT, we envision that the brink of the network is changing from facts patron to information manufacturer as well as facts client. In this paper, we attempt to make a contribution to the concept of edge computing in IoT-enabled Blockchain. IoTenabled Blockchain frameworks slightly help simultaneous execution of a couple of applications and platform independence. These frameworks take advantage of Cloud assets for facts storage and regularly compel electricitylimited IoT devices to procedure the raw data. To lessen the management overhead, current frameworks apply centralized techniques that eventually degrade the QoS. They additionally confine the attention to few safety aspects which results in increase in the vulnerability of the incorporated surroundings. As a solution to those issues, we suggest a energy efficient and QoS-aware decentralized blockchain (EEQA-DBC) in fog computing. The proposed EEQA -DBC disposes the usage of a relied third party and removes the hassle of centralized blockchain. The proposed EEQA-DBC eliminates the need for consensus techniques by utilizing the trust evaluation concepts based on permissioned blockchain concepts to match the requirements of distributed architecture. This paper suggests the novel security evaluation authentication scheme and discusses how the scheme achieves security desires (of personal, integrity, and availability), and is able to triumph over eavesdropping, replay, and denial of service (DoS) attacks. Given the significant security and privacy benefits on offer, the proposed method significantly outweighs by consuming as low as 0.88 mj overheads as compared to standard blockchain.
