Abstract:
This paper concerns multi-hop networks with
multiple physical interfaces, and more particularly with
multiple radios. For these networks, we investigate the
advantage provided by the presence of multiple radios and
specifically their impact on metrics such as link connectivity
and network diameter and their resilience to link failures, and
the length of shortest paths. Our results show that "super
additivity" properties for the metrics investigated can be
achieved by activating the multiple radios available at the
nodes. For instance, we show that topologies that with respect
to one radio have link connectivity λ1 and according to the
other radio have link connectivity λ2, when combined into
one multi-radio network yield a link connectivity which is
> λ1 + λ2. Two different topology formation algorithms are
investigated for single-radio networks and the advantage of
their composition into a multi-radio network is demonstrated
via extensive simulations in realistic scenarios.
