Query: Experimental Evaluation of Multihop Cellular Networks using Mobile
  Relays   Future wireless networks are expected to provide high bandwidth multimedia
services in extended areas with homogeneous Quality of Service (QoS) levels.
Conventional cellular architectures might not be able to satisfy these
requirements due to the effect of surrounding obstacles and the signal
attenuation with distance, in particular under Non Line of Sight (NLOS)
propagation conditions. Recent studies have investigated the potential of
Multi-hop Cellular Networks (MCNs) to overcome the traditional cellular
architecture limitations through the integration of cellular and ad-hoc
networking technologies. However, these studies are generally analytical or
simulation-based. On the other hand, this paper reports the first experimental
field tests that validate and quantify the benefits that MCNs using mobile
relays can provide over traditional cellular systems.
