Abstract: In order to improve the reliability of multi-hop data transmission in industrial wireless ad-hoc network, as for the complicate and bad environment of industry and radio frequency, this paper using the feedback information of link quality and proper error control method, dynamic decomposition and combination mechanism is put forward. At the same time, a cross-layer optimisation scheme of medium access control (MAC) protocol, namely highly reliable carrier sense multiple access with collision avoidance (HR-CSMA/CA) protocol, for data transmission is proposed in this paper, which is a trade-off between energy conservation and throughput, to improve the reliability of data transmission. Eventually the simulation results show that the proposed MAC protocol is superior to CSMA/CA in improving the overall performance of industrial wireless ad-hoc network, especially in the reliability of data transmission, throughput and energy conservation.
