The MAC Protocol Optimization of Industrial Wireless Ad-hoc Network

This paper focuses on the study of MAC protocol in industrial wireless ad-hoc network, aiming at improving the fairness of industrial wireless ad-hoc network and quality of service (QOS). As a result, Hybrid Bi-channel Improvement of CSMA/CA mechanism and Dynamic Time Slot of TDMA mechanism MAC (B-T-MAC) is proposed. This protocol using the super frame structure, adopts the methods of bi-channel improvement and dynamic slot to optimize and improve CSMA/CA and TDMA mechan QOS ism respectively. The simulation results show that B-T-MAC can effectively enhance the overall performance of industrial wireless ad-hoc network, which outperforms Hybrid CSMA and TDMA MAC (C-T-MAC) significantly in throughput and time delay

Automatic Measurement and Monitoring Technology for Oil Well

Measurement technology of oil well develops and improves constantly at present. Reducing operation cost and energy consumption and improving efficiency of labor provides reliable technical guarantee for simplifying and optimizing ground process system. According to the needs of parametric measurement and monitoring for oil well, the paper combines with actual situation of the second factory in Dagang Oilfield, the second factory proposes the research on automatic measurement and monitoring technology for wireless oil well and application project, and scientific and information department in Dagang Oilfield ratifies the project. The paper studies automatic measurement and monitoring technology for wireless oil well, and evaluates the economic and social benefit
