Abstract: “The much research progress has been made in network capacity analysis of ad-hoc networks, WMNs have not been fully explored due to the difference between WMNs and ad-hoc networks. The result about network capacity and optimum node density of ad-hoc networks may not directly be applied to the WMNs because both stationary and mobile ad-hoc nodes exist in WMNs. In last decade much research has been carried out to study the capacity of ad-hoc networks which can be adopted to investigate the capacity of WMNs. In this topic we used two techniques, multi- channels per radio and multi- radios per node. These techniques can be used in WMNs to increase its capacity. In Wireless Mesh Networks each mesh node equips with multiple 802.11 network interface cards (NICs). The central design issues of this multichannel WMN architecture are channel assignment and routing.”
