Issues, Challenges and Techniques in WSN for Performance Enhancement in Underground Coal Mining
Recently, technological growth has gained huge attraction and it is widely adopted in various real-time application systems/ this increasing growth has improved the communication technology by developing small and tiny sensors for information gathering and transferring by consuming less energy in real-time systems. These type of sensor systems are known as wireless sensor network which are used widely in real-time applications such as environment monitoring, traffic monitoring and bio-medical applications etc. In this work, we have focused on the coal-mine monitoring system which can provide the security for mine workers. Mine monitoring systems require an automated process to obtain the information about mine-roof and its convergence along with time which can be used for safety of miners or workers. In order deal with this, wireless sensor network based study is considered as base application. This article presents various recent approaches which helps to improve the wireless communication system such as energy aware routing, wireless sensor network localization etc. A comparative study is presented based on these aspects of wireless sensor network which shows that still the performance of WSN can be improved which can be incorporated with coal-mine monitoring system.
