Wireless Mesh Infrastructure for Ubiquitous Voice and Video

Here is to propose a demonstration of opportunistic wireless mesh networks for broadband wireless Internet access, supporting real-time services, e.g., of voice and video. The enabling technology is of the large-scale cognitive networking, which opportunistically utilizes network resources including both spectrum bandwidth and mesh radio (station) availability. We further demonstrate that: (1) vast saving in the deployment/planning costs of wireless mesh networks can be achieved by establishing fluid networks without predetermined topology; (2) Better (opportunistic) network resource utilization can be achieved to establish reliable communications over multiple wireless hops. The network performance therefore reaches its instantaneous maximum.
