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 significantly in throughput and time delay.
