Nowadays, sensors inserted in mobile applications are used for gathering data for an explicit assignment that can effectively save cost and time in crowd sensing networks (CSNs). The true value and essence of gathered statistics depend on the participation level from all the members of a CSN, i.e., service providers, data collectors, and service consumers. In comparison with the centralized conventional mechanisms that are susceptible to privacy invasion, attacks, and manipulation, this article proposes a decentralized incentive and reputation mechanism for CSN. The monetary rewards are used to motivate the data collectors and to encourage the participants to take part in the network activities. Whereas the issue of privacy leakage is dealt with using Advanced Encryption Standard (AES128) technique. Additionally, a reputation system is implemented to tackle issues like data integrity, fake reviews, and conflicts among entities. Through registering reviews, the system encourages data utilization by providing correct, consistent, and reliable data. Furthermore, simulations are performed for analyzing the gas consumed by smart contracts. Similarly, the encryption technique is ratified by comparing its execution time with other techniques that are previously used in literature. Lastly, the reputation system is inspected through analyzing the gas consumption and mining time of input string length.

基于区块链的人群感知网络激励和声誉机制

如今，插入移动应用程序的传感器用于收集数据以进行显式分配，可以有效地节省人群感知网络 (CSN) 的成本和时间。收集的统计数据的真正价值和本质取决于 CSN 的所有成员（即服务提供者、数据收集者和服务消费者）的参与程度。与容易受到隐私侵犯、攻击和操纵的中心化传统机制相比，本文提出了一种去中心化的 CSN 激励和声誉机制。货币奖励用于激励数据收集者并鼓励参与者参与网络活动。而隐私泄露问题则使用高级加密标准 (AES128) 技术处理。此外，实施声誉系统以解决数据完整性、虚假评论和实体之间的冲突等问题。通过注册评论，系统通过提供正确、一致和可靠的数据来鼓励数据利用。此外，还进行了模拟以分析智能合约消耗的气体。类似地，通过将​​其执行时间与以前在文献中使用的其他技术进行比较来批准加密技术。最后，通过分析输入字符串长度的gas消耗和挖掘时间来检查信誉系统。执行模拟以分析智能合约消耗的气体。类似地，通过将​​其执行时间与以前在文献中使用的其他技术进行比较来批准加密技术。最后，通过分析输入字符串长度的gas消耗和挖掘时间来检查信誉系统。执行模拟以分析智能合约消耗的气体。类似地，通过将​​其执行时间与以前在文献中使用的其他技术进行比较来批准加密技术。最后，通过分析输入字符串长度的gas消耗和挖掘时间来检查信誉系统。
