Abstract
At present, wireless communication networks obtain preliminary application in underground metal mines, but the problems of anti-interference ability and communication capability generally exist. With regard to this situation, this paper proposed an IEEE 802.11n based multi-channel MAC protocol (MC-MAC), which supports multi-channel dynamically switching by evaluating real time channel packet received rate. MC-MAC can improve wireless networks’ data throughput, anti-interference ability, and communication reliability. To evaluate the practical performance of MC-MAC, This paper designed and implemented an wireless access point based on IEEE 802.11n as testing platform, experimental results show that MC-MAC can provide 193Mbps physical links rate and improve network anti-interference ability effectively, it is suitable for underground metal mine applications.
