Abstract:
In order to understand the impact of the mobility patterns on the performance
of routing protocols, it is essential to estimate the mobility patterns of mobile nodes
in a network. Mobility patterns can be estimated with the help of particular
mobility models. In a mobile network, a route is required between a source and
destination prior to any transmission. Route between the source and destination is
discovered by using some routing protocol. A change in mobility pattern may lose
the best existing available route due to link failures. Multipath routing provides
fault tolerance against such link failures. Multi-path routing known as Multipath
Dynamic Address Routing (M-DART) based on Distributed Hash Tables (DHTs),
Multipath Optimized Link State Routing protocol (MPOLSR), and Ad Hoc
On-Demand Multipath Distance Vector protocol (AOMDV) are considered robust
under mobile networks. Mobility pattern in a network may impact the performance
of multi-path routing, thus, it is important to study the impact of various
mobility models on the performance of M-DART, MPOLSR, and AOMDV. This
analysis can be used to improve the performance of multi-path routing in different
network scenarios. In this thesis, I have analyzed the impact of a range of mobility
models on the performance of M-DART, MPOLSR, and AOMDV with the help
of extensive experiments in different network scenarios.
