Wireless relay placement optimization in underground room and pillar mines

Abstract

For the implementation of real-time underground monitoring, communication and tracking, the deployment of wireless communication backbone inside underground mines has got the attention of the researchers in the recent decade. For wireless system deployment in the permanent structure of underground mines, wired communication backbones are appropriate as permanent districts serve for a longer time. However, for temporary openings where service life is for few months or weeks, communication backbone with wireless relay nodes may come out to be more economical as wireless relay nodes give flexibility with deployment, rearrangement and easy retreat. In recent literature multiple approaches of optimal relay node placements are available. However, the choice of best approach for an application is dependent on the specific requirement and constraints of that particular application site. This paper, we discuss on necessary requirements and constraints of wireless relay placement planning in an underground room and pillar mines. Considering the requirements and constraints that are discussed, an optimization approach for wireless relay placement in an underground room and pillar mines using network theory has been proposed in this paper.

Modified Binary Particle Swarm Optimization Algorithm in Lot-Splitting Scheduling Involving Multiple Techniques

“…This calls for improvement of the standard PSO. In 1997, Kennedy and Eberhart proposed the BPSO based on the discrete search space, which works well in solving discrete combinatory optimization problems [12][13][14].…”

Energy‐Spectral Efficiency Optimization in Wireless Underground Sensor Networks Using Salp Swarm Algorithm

“…Swarm optimizations and genetic algorithms are the two main categories of metaheuristic algorithms. In the literature, the genetic algorithm (GA) had been used in WUSN optimization to achieve better network lifetime [20,21]. In [20], the wireless sensor nodes of underground mine network are clustered based on GA to obtain a green communication environment.…”

“…In [20], the wireless sensor nodes of underground mine network are clustered based on GA to obtain a green communication environment. Likewise, the relay node placement in underground room and pillar mines is optimized using GA in [21]. In [22], a single-hop-based routing algorithm for multiple mobile sinks in WSNs is exhibited.…”

“…The method is composed of two parts: the park position selection based on the Particle Swarm Optimization (PSO) and multipath scheduling for mobile sinks based on the GA. The studies [20][21][22] target reaching minimized energy and extended network lifetime in WSNs. In [23,24], the Gravitational Search Algorithm (GSA) is used to enhance the energy efficiency of WSNs.…”
