Multiple-input-multiple-output (MIMO) technology, which is a recent breakthrough in wireless communications, has been shown to significantly improve channel capacity in single-user systems. However, obtaining a rigorous understanding of the possible MIMO gains in multihop networks is still an open topic. One grand challenge is that multihop wireless networks are interference limited and that the interference...
We consider a relay network having K source-destination pairs. Finding the capacity region of such a network with multiple unicast sessions is in general difficult. By focusing on a special class of such networks, we show that the capacity can be found. Namely, we consider a linear finite-field channel model, which can model interference in the network. Furthermore, we assume time-varying channels...
In multihop wireless networks each node is equipped with multiple radio interfaces, and multiple channels are available for communication. One of the major problems in such networks is the capacity reduction due to the interference among multiple simultaneous transmissions. In order to effectively minimize interference, this paper proposes a QoS routing protocol CATR based on channel assignment and...
