A Transmitting Algorithm Based on Traffic Redirecting in Industrial Energy-efficient Multi-hop Wireless Networks

In recent years, energy efficiency has become a major bottleneck for sustainable development of the industrial communications network, how to achieve energy-efficient communication has become a hot topic for researchers. This paper focuses on industrial energy-efficient multi-hop wireless networks proposing a transmitting algorithm based on traffic redirecting (TRTA). The design of traditional mobile multi-hop wireless network only consider either network efficiency or minimum energy networks to maximize network efficiency. In this paper, to make up for shortcomings of previous studies, proposed an algorithm to maximize network efficiency for the novel pub-sub transmission mode of industrial network. The TRTA uses the technology of network flow sensing, according to the information of traffic network to get traffic load of the network. And then using the flow redirecting method to redirect the traffic on low-load path to other links with higher utilization rate but not heavy, in order to improve the whole energy efficiency of the network. Simulation in a multi-hop wireless networks with pub-sub transmission mode, the results show that the proposed algorithm has lower energy consumption and higher network efficiency, network performance has been significantly improved.
