"Quality of Service Framework for Mobile Ad Hoc Networks"

Abstract

Providing guaranteed quality communications in mobile ad hoc networks
(MANETs) is a tremendously challenging task due to a lack of resources in
the network in addition to frequent changes in the network topology due to
node mobility. Although extensive research has been done in this area in
the context of Internet and other wireless infrastructure networks, their
results are hardly, if at all, suitable for MANETs. Providing a Quality of
Service (QoS) solution for MANETs requires the interaction and cooperation
of several components across all layers of the protocol stack. These
components include: QoS routing protocols, an admission control scheme, a
resource reservation scheme and a QoS capable medium access control (MAC)
protocol. This thesis proposes a framework and protocols to support QoS in
MANETs on a per class basis using Differentiated Services framework. This
proposed scheme integrates the above-mentioned components while taking
into account the characteristics of MANETs, viz., bandwidth constraint and
dynamic topologies for providing differentiation between two service
levels: premium guaranteed service or expedited forwarding and a best
effort service. Extensive simulations show the effectiveness of the
proposed framework in providing QoS under different traffic loads and
mobility patterns.
