Multi-Antenna Utilization Scheme to Prevent Packet Congestion in Wireless Mesh Networks
Norihiko SATO, Takeo Fujii · IEICE Transactions on Communications · 2010
In this paper, we investigate a multi-packet transmitting and receiving wireless mesh network that uses a multi-antenna set on each node in the network. In wireless mesh networks for accessing the Internet, the target of all traffic generated from distributed nodes is a gateway (GW). Therefore, many packets are concentrated around the GW and the communication channel around the GW is crowded. To prevent packet congestion around the GW, we propose setting an adaptive array antenna on the GW and the relay nodes. We also calculate an appropriate number of antenna elements considering the fair traffic over the whole region, to prevent packet congestion at each node.
