Indoor Coverage Performance Comparison between IEEE 802.11g and IEEE 802.11 ah of Wireless Nodes in M2M Network

This paper mainly presents the indoor coverage performance and time delay comparison between IEEE 802.11g and IEEE 802.11 ah of wireless sensor node in Machine to Machine(M2M)network. Firstly, three key problems about the development of M2M network are proposed in order to bring out why IEEE chooses to release IEEE 802.11ah standard and its current situation and tendency. And also, we simply introduce the standard of IEEE 802.11g. Secondly, the paper illustrates the indoor coverage performance and time delay comparison of wireless sensor nodes according to different indoor path loss models respectively for Sub 1GHz and 2.4GHz ISM band. And numeral simulation results and simulation results are respectively offered to depict sensor nodes’ coverage and the time delay.
