| Research Abstract |
A Study of Scalable Wireless Mesh Network for High-Capacity Data Transmission We studied the architecture, protocols, and design optimizations of wireless Internet-access mesh networks to improve the communication performance. First, we proposed the scalable architecture by adopting two types of access points (APs) and two types of AP clusters. Then, we proposed the fixed backoff-time switching method of ensuring the necessary bandwidth for each link, and implemented it on a network simulator and a Linux-PC. Finally, we proposed routing and active AP selection algorithms to efficiently apply the IEEE802.11n protocol.
