Exploiting Industrial Big Data Strategy for Load Balancing in Industrial Wireless Mobile Networks
Abstract
In the era of big data, traditional industrial mobile wireless networks cannot effectively handle the new requirements of mobile wireless big data networks arising from the spatiotemporal changes of a nodes traffic load. From the perspective of load balancing and energy efficiency, Industrial Big Data (IBD) brings new transmission challenges to Industrial Wireless Mobile Networks (IWMNs). Previous research works have not considered dynamic changes related to the traffic and mobility of IWMNs. In this paper, using an IBD technique, we propose a novel second deployment and sleep-scheduling strategy (SDSS) for balancing load and increasing energy efficiency, while taking the dynamic nature of the network into consideration. SDSS can be divided into two stages. In the first stage, changes in the traffic of every network grid its maximum traffic load at different times are calculated using big data analysis techniques. In the second stage, a second-deployment method for the Cluster Head Nodes (CHNs), based on each grids maximum traffic load, is adopted. To save energy, based on their position and traffic states, a sleep-wake scheduling is presented for the CHNs. Simulations results verify the effectiveness of this methodology to save energy and obtain a traffic balance which is more efficient than obtained through traditional methods.
Existing System:
Existing approaches and algorithms are not applicable in practical scenarios in the industrial domain. In industrial applications, the traffic load of the network in the presence of big data will change with time because of the changes in the mobile nodes and the communication activities. While the use of big data brings advantages and conveniences, it also raises multiple challenges to be addressed in the framework of smart factory and industry 4.0.
Proposed System:
In this paper, we aim to address some of these challenges. Our objective is to develop an algorithm with the following properties: 1) The algorithm can balance the dynamic changes in the traffic load; 2) The algorithm is energy efficient. Hence, in the paper, we propose a new second-deployment strategy based on the timing feature of the network load. To save energy, we adopt a sleep-wake scheduling approach, based on the location and the traffic load of the access nodes. Through the results of our simulations, we verify the efficacy of this proposed methodology and demonstrate that it can improve the energy efficiency and achieve traffic balance.
Conclusion
The greatest challenges of wireless networks for big data in the context of a smart factory are a) mobile nodes and b) dynamically changing heavy traffic load. These can cause imbalances in traffic and energy consumptions of cluster head nodes in hierarchical networks. In this article, we introduced a methodology for incorporating deployment and sleep scheduling of such nodes in an industry 4.0 factory. Due to the movement of the mobile nodes, the traffic load of each grid will change dynamically with time. By analyzing the historical records of traffic load for each grid using an industrial big data strategy, network features can be extracted and the peak in traffic and the corresponding time can be identified. Using a distributed genetic algorithm to obtain an optimal traffic balance level, we second-deploy the cluster head nodes. At last, based on the service time model, we propose a novel sleep-wake scheduling method. Simulation results demonstrate that the proposed method performs better than traditional methods, and the performance advantages increase with an increase in the number of nodes. Aside from obtaining a good balance and effective communication, the proposed method is also able to decrease the network latency.
