Performance Optimization in Single Channel Directional Multi-Interface IEEE 802.11s EDCA Using Beam Prioritization
Single channel multi-interface IEEE 802.11s Wireless Mesh Network(WMN) is a promising technology for increasing spatial reuse of wireless channel using high gain directional antennas. Use of single channel in WMN is advantageous for providing different services (like community mesh networking, vehicular mesh networking, etc.) by different frequency channels so that several wireless networking services can co-exist. However, for effective use of multi-interface multi-beam directional antennas in single channel environment, proper scheduling of interfaces and prioritization among different beams are required to minimize channel interference.
