“…The above method increases bandwidth of the system and is very suitable for multi-hop transmission, but it doesn't consider the QoS of service. Literature [14] proposes a continuous collision free MAC adaptive algorithm UCFA using a deterministic backoff method combined with fixed TDMA time slot scheduling strategy, it can guarantee a collision free data transmission without the need to consider the flow type and the number of terminals.…”

WiFi-MESH wireless network which are mainly based on the 802.11 protocols are developed quickly in recent years. The principle features, difficulties, directions and application schemes of the key technologies of WiFi-MESH systems, including MAC mechanisms and routing protocols, are analyzed and discussed. It can be concluded in the paper that the TDMA mechanisms based on 802.11 should be developed further for avoiding the collisions in essence, and the new BATMAN-adv routing protocol based on OSI architecture layer two may raise the performance of the systems more significantly than the HWMP routing protocol. Finally, some new technologies which could be used in WiFi-MESH are discussed.

The ambitious goal of the upcoming IEEE 802.11ax (HEW) standard for wireless LANs (WLANs) to enhance throughput by four times (and beyond), compared with IEEE 802.11ac, demands a radical improvement of present medium access control (MAC) functionality. To this end, a promising paradigm would be a graceful migration towards new MAC protocols which incorporate higher certainty in their decisions. However, this requires adequate information to be available to the devices, which in turn incurs excessive costs due to information exchange between devices. Also, scalability becomes an issue for emerging dense networks. In this paper, we take a step forward by proposing an opportunistic MAC (OMAC), which restrains these costs, while increasing throughput of the new generation HEW. OMAC eliminates overhead costs by solely relying on the local capability of devices in measuring signal activities in the channel. A particular OMAC node continually collects and records the received signal strengths (RSS) overheard from the channel, and regards each individual RSS level as being transmitted by a unique node without the need to know the actual identity of the node. The OMAC node uses this knowledge to select a recorded RSS as its reference, and triggers a desired transmission policy whenever a transmission with an RSS sufficiently close to this reference RSS is detected. Our results, obtained using simulations, indicate that OMAC improves the throughput performance significantly, and that the performance gain increases with an increase in network density.
