ATOM: Adaptive Transport Over Multipaths in Wireless Mesh Networks
Source: University of Bern
In this paper, the authors propose the ATOM (Adaptive Transport Over Multipaths) architecture to enable real-time communications in Wireless Mesh Networks (WMNs). WMNs provide robust communication facilities which are even available when certain other systems fail. On the other hand, real-time applications (e.g., IP telephony, video conferencing) in WMNs suffer from transmission errors, high delays, etc. caused by the unreliable wireless medium. ATOM reduces these effects by using path diversity and multi-stream coding. At the session establishment, ATOM decides on the used parameter set (encodings, paths, etc.) considering current network conditions and collected historic data.
