ABSTRACT
Most limitations in mechanisms geared at achieving
quality-of-service (QoS) in wireless ad hoc networking can be
traced to solutions based on mapping wireless networks to a
wireline paradigm of nodes and links. We contend that this
paradigm is not appropriate since links are not physical entities
and do not accurately represent the radio frequency (RF) media.
Using the link abstraction makes arbitration of the use of the RF
media cumbersome leaving only overprovisioning techniques to
deliver QoS. In this paper, we argue that an appropriate paradigm
should match the physics of the network. The critical resource
is electromagnetic spectrum in a space; in turn, this results in a
complex paradigm since the part of the spectrum-space that each
node wants to use is unique to that node and its destination and
will overlap with parts that other nodes may want to use creating
interdependences among nodes. This paper describes protocol
approaches for access and routing that seek solutions within
this wireless paradigm. Access is arbitrated using synchronous
signaling and topology is resolved through the dissemination of
node states. This approach provides an intuitive framework that
provides mechanisms that can be exploited to arbitrate RF media
use and implement traffic engineering techniques to deliver QoS.
Our proposed approach provides a novel way of tracking the
state of the network that can serve as a unified state dissemination
mechanism to simultaneously support routing, multicasting, and
most QoS heuristics.
