An Opportunity Transmission Mechanism in Mobile Crowd Sensing Network based on SSIS Model
2018 IEEE 22nd International Conference on Computer Supported Cooperative Work in Design ((CSCWD)), 2018Co-Authors: Tao Zhou, Wuyungerile Li, Zhendong XuAbstract:Mobile Crowd Sensing Network (MCSN) is a new sensing mode in the Internet of Things by taking advantage of individual's mobile device with multiple sensors to collect some specific data for certain applications. There are two modes of Transmission Mechanism in the existing systems: one is end-to-end mode via the cellular network and the other is opportunistic Transmission via short-range wireless communication technology. Due to the higher cost, the former is not conducive to enlarging users'participation. This paper focuses on the mode of the latter to build a new opportunistic Transmission in MCSN. Differently from most existing studies, i.e. preference-aware and energy-aware, this paper proposes an opportunistic data Transmission Mechanism based on SSIS model (a socialization SIS epidemic model), who can transfer the sensing data to the platform by forwarding step by step without extra cost. Specifically, firstly, SSIS model is defined based on SIS epidemic model by social information in MCSN. Additionally, SSIS model is used to analyze the social relationship of mobile sensing nodes in MCSN to obtain a social relational table. Finally, the social relational table is used to improve the Spray and Wait (SW), which is a typical opportunistic Transmission Mechanism, to guide the source node which performs the task of sensing to propagate the sensing data selectively to other nodes until it reaches the destination node which can send the data to the platform. Simulation results show that the performance of data Transmission can be further improved by using the proposed Mechanism in comparison with SW, Epidemic and Prophet.

Opportunistic Transmission Mechanism Based on SI in Mobile Crowd Sensing Networks
Proceedings - 2017 IEEE International Conference on Software Quality Reliability and Security Companion QRS-C 2017, 2017Co-Authors: Bing Jia, Shuai Liu, Tao Zhou, Zhendong XuAbstract:Mobile Crowd Sensing Networks (MCSN) treat the ordinary users with their mobile devices as the basic sensing units, and leverage them to distribute complex social sensing tasks and collect sensing data with each other by the mobile networks. To improve the efficiency and the feasibility of data sensing, collection and Transmission in MCSN, we propose an opportunistic data Transmission Mechanism based on SI epidemic model. Firstly, the SI epidemic model is used to analyze the social characteristics of MCSN, and obtained the table of the evolutionary relationships between the nodes based on social relationship. Secondly, the evolutionary relationships is quantified and added to the opportunistic routing as the additional information, to guide the nodes in MCSN to reach the target mobile node successfully by using the opportunistic data Transmission Mechanism in the mode of "storage + carry + forward". Simulation results show that the performance of data Transmission Mechanism can be further improved by using the SI epidemic model in the opportunistic routing. The proposed Mechanism has higher success rate of delivery as well as the lower forwarding costs without significant increase in the time costs.

Original design on the power Transmission Mechanism of a twin-rotor piston engine
2011 Second International Conference on Mechanic Automation and Control Engineering, 2011Co-Authors: Hao Deng, Weiyang ZhangAbstract:In order to increase the power density of the piston engine, the power Transmission Mechanism of a twin-rotor piston engine based on differential velocity principle is introduced. Firstly, the precept of the engine principle is developed, and the velocity of the rotors is designed, then the structure and the kinematic simulation of the power Transmission Mechanism are derived. The results show that the combined Mechanism composed of the hypocycloidal planet gear Mechanism and the crank rock Mechanism can satisfy the design principle of the twin-rotor piston engine, the number of the airtight cavity and its vary is related to the gear ratio, the power frequency of the engine is increased obviously.

Study on the power Transmission Mechanism of a twin-rotor piston engine based on cyloid
2011 International Conference on Consumer Electronics Communications and Networks (CECNet), 2011Co-Authors: Hao Deng, Hu ChengAbstract:In order to increase the power density of the piston engine, the power Transmission Mechanism of a twin-rotor piston engine based on cycloid is introduced. The twin-rotor piston engine has a number of advantages compare to other piston engine type. The combination method of its unique power Transmission Mechanism which use the cycloid and the crank-rocker Mechanism creating a cyclic rotary motion superposed on uniform rotary motion of the rotor is proposed. Two types of this Mechanism designed by the method are derived. This has been examined through the kinematic analysis. The results show that this engine Mechanism is compact and has the multiple power strokes per revolution of the flywheel.

monetary policy and the Transmission Mechanism in thailand
Journal of Asian Economics, 2003Co-Authors: Piti Disyatat, Pinnarat VongsinsirikulAbstract:Abstract This paper studies the monetary Transmission Mechanism in Thailand. It examines the degree of pass-through from money market rates to retail rates, attempts to quantify the lags associated with monetary policy shocks, and investigates the channels through which these shocks are propagated. The empirical results point to a Transmission Mechanism in which investment is particularly sensitive to monetary shocks and banks act as an important conduit for monetary policy to real activity. They also suggest, however, that problems in the corporate and banking sectors may have undermined the monetary Transmission Mechanism over the last few years.
