Abstract EN
There is an emerging need for realizing real-time quality of service (QoS) over multihop wireless communications in large-scale wireless networks.
The applications can include wireless mesh infrastructure for broadband Internet access supporting multimedia services, visual sensor networks for surveillance, and disaster-relief networks.
However, a number of challenges still exist as revealed by recent works, where the dataflow QoS performance such as throughput and end-to-end delay can degrade fast with the number of wireless hops.
We propose to use large-scale cognitive networking methods to resolve the wireless multihop challenges.
By the cognitive-networking concept, data packets travel along opportunistically available paths in the network with opportunistically available spectrum in every hop.
Reliable end-to-end communications can be achieved for real-time services, where we show that (1) dataflow throughput can be independent of any number of wireless hops, (2) end-to-end delay and delay variance increase linearly with the number of wireless hops, and (3) delay variance decreases to zero with higher network density.
These results are supported by analysis, simulations, and experiments.
