Mobile nodes are interconnected by multihop routing
paths consist of unstable radio links in ad hoc wireless
network. It is complex and difficult to provide QoS
routing in such network because of imprecise network
information, insufficient bandwidth and dynamic
topology. For improving network stability and
throughput, multipath routing protocols are proposed. A
sender node will discover multiple disjoined routing
paths and spread traffic into multiple streams according
to their delay or bandwidth. For real-time streaming,
unstable throughput or insufficient bandwidth will
invite unexpected delay or jitter if it is a multimedia
streaming. Some multipath routing protocols pre-evaluate available bandwidth of paths and select enough
total bandwidth from them if real-time applications
demand for QoS constraint. For minimizing the cost of
these paths, a path with smaller hopcounts will be prior
selected. These disjoined paths are general too closed
with each other and the total throughput cannot just be
sum up because of "paths interfering". Discovering and
selecting multiple high-interfering paths is ineffectual
and the total available bandwidth is not precise. In this
paper, we proposed an interfering-aware QoS multipath
routing protocol for QoS-constraint multimedia and
real-time applications in ad hoc wireless network. We
apply a scheme to evaluate available bandwidth
according to the network capacities with different Media
Access Control (MAC) protocols. A concept of
"Interfering ratio" of multipath will be discussed and
we evaluate the stability and throughput improvement
by simulations.
