We study the routing problem of scalable video coding video streaming over
wireless mesh networks. In contrast to most of the conventional routing al-
gorithms, our proposal focuses on optimizing users’ satisfaction. The mean
opinion score –an indicator of quality of experience (QoE) in video streaming–
is utilized to assess the quality of routes in wireless mesh networks. The ob-
jective is to optimize the overall user experience in the network. Conventional
routing approaches do not consider QoE and are not optimal with respect to
user experience. Moreover, some centralised approaches are not scalable and
require significant computational resources. The latter disadvantage can be
overcome using distributed approaches. This paper presents a QoE-based co-
operative distributed routing approach. Among distributed cooperative opti-
mization schemes, AD 3 is highlighted as one of the most efficient because of
its fast convergence. The contributions of this paper are as follows: we encode
the original problem into a factor graph and optimize the number of exchanged
messages; we propose a partially distributed routing scheme based on OLSR
and AD 3 ; and we propose a distributed decoding algorithm in order to find a
feasible solution. Our thorough simulation results confirm the advantages of the
proposed scheme.
