Abstract. At present, most of the transaction operations are required in the heterogeneous network environment. The transaction operations not only guarantee transaction implemented correctly and effectively, but also keep transactions under the different environment of consistency and integrity. This paper mainly introduces Lock schemes for resolving the concurrent access conflicts in distributed transaction and the control methods of lock granularities applied for different cases are proposed. It provides solutions to concurrent transaction congestion in the network environment, while optimizing the performance of distributed transaction.
A large number of advanced technology dedicated to research and development smart home applications in the IOT environment, especially using of open-source Arduino and ZigBee wireless communication protocol to build a interoperability smart home system have major value. In the designing of this smart home, researching on the characteristics of ZigBee technology and network topology, making a special effort to analyze the ZigBee protocol specification.It mainly studied and designed the smart gateway based on CC2530 and Arduino, that realize the communication of each devices, and achieve the remote monitoring and wireless control in the home. In addition, the performance test and power analysis are completed, which provides a strong guarantee for the further development of smart home.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
