Optimal number of radio interfaces in wireless mesh network

Wireless mesh networks (WMNs) offer many advantages in terms of reliability, scalability and connectivity. These networks provide multiple paths between nodes. Traditionally, WMNs used nodes equipped with a single radio interface. In single radio WMNs exist many limitations, such as lower throughput and limited usage of the available wireless channels. In this paper, we present the effect of the number of interfaces increasing on WMN capacity. The WMN simulation model was created, where the optimal number of interfaces for WMNs was determined to improve chosen quality of service (QoS) parameters in service with constant bit rate (CBR) requirements.
