Abstract
We present a link layer protocol called the Multi-radio Uni-
fication Protocol or MUP. On a single node, MUP coordi-
nates the operation of multiple wireless network cards tuned
to non-overlapping frequency channels. The goal of MUP
is to optimize local spectrum usage via intelligent channel
selection in a multihop wireless network. MUP works with
standard-compliant IEEE 802.11 hardware, does not require
changes to applications or higher-level protocols, and can
be deployed incrementally. The primary usage scenario for
MUP is a multihop community wireless mesh network, where
cost of the radios and battery consumption are not limiting
factors. We describe the design and implementation of MUP,
and analyze its performance using both simulations and mea-
surements based on our implementation. Our results show
that under dynamic traffic patterns with realistic topologies,
