【Abstract】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 to 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 to propose a routing protocol for performing efficient communication between network nodes while simultaneously avoiding void holes between ordinary sensor nodes and a sink node. Furthermore, to 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 to 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 storage. The simulation results show that PoA performs 13% better than proof of work consensus algorithm. The proposed routing protocol and trust model are validated in terms of gas consumption, throughput, nodes' status and energy consumption.

【标题】使用区块链的无线传感器物联网安全高效的信任模型
【摘要】无线传感器物联网 (WSIoT) 由于部署在恶劣和无人值守的环境中，因此面临各种挑战，例如不可靠的数据通信、较低的成本效率、安全问题和高能耗。此外，由于空洞和网络部署不平衡导致节点的快速能量消耗，对网络性能产生不良影响。为了克服上述问题，本文提出了一种基于区块链的 WSIoT 信任模型。此外，Dijkstra算法用于提出一种路由协议，用于在网络节点之间进行高效通信，同时避免普通传感器节点和汇节点之间的空洞。此外，为了在网络中提供透明度，节点执行的所有交易都以不可变的方式记录在区块链中。此外，权威证明（PoA）共识算法用于验证和添加区块中的交易。此外，在 WSIoT 中使用分布式平台（称为行星际文件系统）来实现可靠且经济高效的存储。仿真结果表明，PoA 的性能比工作量证明共识算法好 13%。所提出的路由协议和信任模型在gas消耗、吞吐量、节点状态和能量消耗方面进行了验证。
