Abstract: In the context of Trusted Attestation System in Cloud Computing Environment the Root of Trust for Attestation plays a vital role for security feature with Trusted Computing. The main aim of trusted attestation process is to provide an effective mechanism for the interconnected public and private systems in a well secured platform using Trusted Platform Module. The mechanism created by the trusted attestation phase gains assurance about data integrity and trustworthiness. The Trusted Attestation System enables the trusted computing functionalities for all authorized users in the current working environment. The Cloud Computing Environment extends the failure rate as attacks on public data and private data for the trusted system. The authenticated integrity state of a trusted system involves the Root of Trust for Attestation (RTA). In the cloud environment an attested user is trusted to behave with the available standard technologies like management of identity, digital signatures, exchange of credential, certificates and management of key. The trusted attestation system in the cloud environment provides Trust as a service (TaaS) for the generation of key. The credential exchange for the trusted environment enhances the facility for Cloud Computing Environment (CCE).

Abstract: In order to bring the potential advantages of directed diffusion routing into full play in wireless sensor networks, the minimum hop routing (MHR) protocol based on directed diffusion is improved, and the MLN (MHR based on Lowest Level Neighbors) routing protocol is presented. In the MLN, by limiting the gradient level width of directed diffusion gradient field, the connectivity of logical topology in wireless sensor networks is enhanced, so that the reliability of data aggregation is improved. At the same time, by changing the data-packet forwarding rule of hop-by-hop in the MHR to the rule of data-packet being priority forwarded by the lowest-level neighbors in the MLN, the real-time performance and the energy efficiency of data aggregation are improved on the premise of high data aggregation reliability. The theoretical analysis and simulation results validate that the MLN routing protocol not only enhances the connectivity, but also improves the comprehensive performances of directed diffusion routing in wireless sensor networks.

Abstract: In order to meet the requirement of positioning accuracy of indoor mobile robot, an indoor localization method based on information fusion is proposed. Firstly，using the Radio frequency identification (RFID) location method to determine the approximate range of the mobile robot's position, in the scope of the current with visual positioning for robot pose information including location coordinates and the deflection Angle; Secondly, using adaptive weighted fusion method to fuse RFID and visual location information; finally, the final result is obtained by Kalman filtering on the location information. The experimental results show that this method can improve the precision of positioning effectively.

Abstract: Some of the largest datasets have strong time components, like machine monitoring, real-time alert and IoT devices, etc. Despite of so many applications of time series data, most storage options are either highly proprietary or worse, relational. Unlike other alternatives, TideDB does not have a data with multiple metrics broken down into multiple data with one metric that increases the pressure on system throughput dramatically, rather its data modeling based on the computed column and tag words index can provide high write throughput, low read latency, and petabytes storage. TideDB has been deployed in production settings on large clusters to manage multiple terabytes of storage at Taide Company. The paper describes the TideDB how to store and organize our time series data from about one hundred thousand devices and millions service modules.
