Abstract
This work proposed the Claim-based Channel Access (CCA) method for IEEE 802.11ah, which is designed for Internet of Things (IOT). The proposed CCA method uses the newly devised Claiming RAW to let those stations having uplinked data frames to claim their intentions for uplinking data frames to reduce collisions. In addition, this work adopted the registered backoff time mechanism, for which a station registers its next backoff time to AP when its current channel access is finished. In this way, AP is able to schedule stations according to their registered backoff time in advance to avoid collisions more effectively. Comparing with the traditional IEEE 802.11ah, the proposed CCA method has the lower collision rate and higher throughput in the network environment having the more number of stations in each time slot for accessing the channel.
