Abstract
A mobile ad hoc network (MANET) is a group of mobile nodes that can
communicate with one another without the need for a fixed infrastructure and
centralized management. MANETs are popular in locations that lack a fixed
communication infrastructure, such as in natural disaster sites and battlefields. The
varying densities of mobile nodes from one sub-area to another are referred to as
non-uniform node densities. The communication between nodes in a network with
non-uniform density faces the challenge of low connectivity, in which nodes are
susceptible to link breakages. Such condition affects the Quality of Service (QoS) in
networks. Typically, a non-uniform node density influences network performance.
For instance, packet delivery ratio is expected to be high in high-density sub
networks and low in low-density sub networks. This thesis proposes a multipath
cluster-based routing protocol (MP-CBRP) to address the problem of low
connectivity in networks with non-uniform density and to improve the QoS for
MANETs. The MP-CBRP is able to avoid traffic congestion and frequent link
breakages in communication by providing load balancing and route failure
protection. Traffic is redistributed among sets of multiple paths. The benefits of these
features allow the MP-CBRP to enhance the QoS for MANETs by reducing delays
and increasing packet delivery ratio and throughputs. Simulation experiments using
the Network Simulator demonstrate the effectiveness of the MP-CBRP in improving
QoS. The performances of the MP-CBRP, cluster-based routing protocol (CBRP),
and Ad hoc on-demand multipath distance vector (AOMDV) routing protocols in the
a non-uniform density (ND) and high density (HD) topologies under the random
waypoint (RWP) mobility model, the reference point group mobility (RPGM) model,
and Manhattan mobility model are evaluated and compared. The simulation results
show that the MP-CBRP achieves the highest performance among the three protocols
by providing end-to-end QoS support in MANETs. The MP-CBRP achieves the
lowest normalized routing load, average delay, and average hop count. Furthermore,
its packet delivery and average throughput are better than those of the CBRP and
AOMDV protocols.
