On Achieving the Maximum Internet Capacity in Wireless Mesh Networks

A Wireless Mesh Network (WMN) is connected by multiple wireless mesh routers that are able to operate multiple channels for increased network capacity. At the same time, the infrastructure such as Internet gateway provides the Internet connectivity and thus the mobile users in the network can access the Internet by multi-hop route of mesh routers. As other wireless networks, the network capacity is a fundamental issue in the WMN. The analytical results in this paper show that the upper bound of network capacity. Only when the number of Internet gateway nodes asymptotically grows with the number of mesh routers, the network capacity achieves significant capacity gain. We theoretically compute the WMN upper bounds of the infrastructure network capacity and its ad hoc capacity as well.
