Multihop transmissions over wireless mesh networks
present limited end-to-end (E2E) data rates, as every hop
waits for an entire packet to arrive before starting retransmission.
That is, the E2E data rate drops when every hop stores and then
forwards packets, thus making such transmissions unsuitable for
multimedia applications. In this work, in order to increase data
rates, we present an ultra-wideband (UWB) radio transceiver
capable of concurrently transmit and receive (cTxRx) packets.
However, concurrently receiving and transmitting comes at the
cost of a channel model with increased interference level. Herein,
we explain a new interference model and propose a transceiver
that compensates for it. We describe the transceiver mathematically
and analyze its performance via simulations. Also, we
demonstrate that the E2E data rate exceeds that of current
multihop transmissions, thus allowing multimedia traffic to be
transmitted over a multi-hop wireless mesh network.
