摘要
En 中文
Wireless Sensor Internet of Things (WSIoTs) face various challenges such as unreliable data communication, less cost efficiency, security issues and high energy consumption due to their deployment in hostile and unattended environments. Moreover, the node's rapid energy dissipation due;
the void holes and imbalanced network deployment has a bad impact on the network performance. To overcome the aforementioned issues, a blockchain based trust model for WSIoTs is proposed in this paper. Moreover, the Dijkstra algorithm is used;
propose a routing pro;
col for performing efficient communication between network nodes while simultaneously avoiding void holes between ordinary sensor nodes and a sink node. Furthermore,;
provide transparency in the network, all the transactions performed by the nodes are recorded in the blockchain in an immutable manner. Moreover, the Proof of Authority (PoA) consensus algorithm is used;
validate and add the transactions in the blocks. Besides, a distributed platform, known as interplanetary file system, is used in WSIoTs for reliable and cost-effective s;
rage. The simulation results show that PoA performs 13% better than proof of work consensus algorithm. The proposed routing pro;
col and trust model are validated in terms of gas consumption, throughput, nodes' status and energy consumption.
