Abstract

Rangkaian sementara bergerak (Mobile Ad Hoc Networks, MANET) merupakan suatu kumpulan nod bergerak yang boleh berkomunikasi bersama tanpa memerlukan sebarang infrastruktur tetap dan pengurusan terpusat. MANET begitu popular dalam keadaan ketiadaan lokasi infrastruktur komunikasi tetap, seperti tapak bencana alam atau medan perang. Ketumpatan nod bergerak yang berbeza daripada satu subkawasan dengan subkawasan yang lain didefinisikan sebagai ketumpatan nod tidak seragam. Komunikasi di antara nod dalam rangkaian ketumpatan nod tidak seragam berdepan dengan cabaran keterikatan yang rendah, yang memungkinkan nod lebih rentan atau suseptibel untuk terputus pautan. Keadaan tersebut akan memberi impak terhadap kualiti perkhidmatan (quality of service, QoS) dalam rangkaian. Secara tipikal, ketumpatan nod tidak seragam boleh mempengaruhi prestasi rangkaian.. Sebagai contoh, nisbah penghantaran paket dijangka tinggi dalam subrangkaian ketumpatan tinggi dan rendah dalam subrangkaian ketumpatan rendah. Tesis ini mncadangkan Kluster Berbilang Laluan berdasarkan Protokol Penghalaan (MPCBRP) untuk mengesan masalah keterkaitan yang rendah dalam rangkaian ketumpatan nod tidak seragam dan untuk menambah baik QoS bagi MANET. 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.
