| dc.description.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. | en_US |
