ABSTRACT
The article presents information on the features of wireless mesh networks (WMNs). Mesh technology promise greater flexibility, reliability and performance over conventional Wi-Fi wireless LANs (WLANs) as all communication among mesh network nodes, and between nodes and clients, is over a radio link instead of cable. WMNs allow anyone with a wireless adapter card in their laptop, tablet or PDA to communicate on a peer-to-peer basis, in addition to accessing a WLAN. A WMN supports multiple paths among network nodes and nodes can be added to increase redundancy. However, like every technology, WMNs also have their weak points. As networks grow, they suffer from bandwidth degradation, radio interference (RF) and per-hop latency. Also, RF interference can affect the devices on a WMN, causing transmission errors. Many WMN devices have omnidirectional antennas, which can be a limiting factor as they propagate a signal in a 360-degree pattern, causing RF interference in network and collisions as the number of users and nodal transmitters increase.
