Abstract
In smart dust IoT environments, a large number of devices with low computing power/resources are deployed to collect surrounding information. There are many issues to consider for an efficient and secure smart dust IoT environment. Sometimes the urgent sensed data needs to be transmitted immediately. In addition, there are potential problems related to security issues since the smart dust IoT systems may be deployed in hard-to-access areas. In this paper, we propose an effective transmission method for two-class sensed data for secure smart IoT systems. We divide the sensed data into two classes which consist of the urgent sensed data class (requiring urgent data transmission) and the normal sensed data class (with a slight transmission delay due to yielding to the urgent data transmission). In addition, for security reasons, the proposed transmission method uses two kinds of blockchains with the following two ledgers: (1) the urgent sensed data ledger, which is a ledger of data that needs urgent transmission; and (2) the normal sensed data ledger, which is a ledger of data that allows some delay. To be specific, the lightweight blockchain based on our earlier work is used for the normal sensed data transmission, whereas the modified conventional blockchain is used for the normal sensed data transmission. The experiments show that the performance of the proposed transmission method is better than the conventional transmission method in almost all sections. There is a 53% performance increase on average with regard to the transmission time. When the ratio of urgent sensed data is 0% (i.e., no urgent sensed data at all), the proposed transmission method is greater improved by as much as about 96%. This means that the lightweight blockchain scheme used in the proposed transmission method for the normal sensed data is very efficient.

Summary
The IoT (Internet of Things) is a concept that includes the close connection between objects and people around them are established on a network [1,2,3,4,5,6,7,8]. Some of the data collected in smart dust IoT environments require very urgent transmissions, while other data allow some delays. In our earlier study [14], we proposed a two-phase data reduction method that reduces the bandwidth in smart dust IoT environments. We propose a two-class data transmission method using two types of blockchains (i.e., a lightweight blockchain and the conventional blockchain) to ensure the security of the smart dust IoT environment and to transmit the urgent data smoothly. We propose in this paper an effective transmission method for two-class sensed data for secure smart IoT systems.
