ATOM: Adaptive Transport over Multipaths in Wireless Mesh Networks
نویسندگان
چکیده
In this paper we 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. Then, after the session establishment, the effect of this decision is continously monitored. If necessary, the decision is adapted.

Many appealing multicast services such as on-demand TV, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. When multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. Designing a good multicast tree to route data packets could enhance the...
