Performance evaluation of multi-path routing under different mobility models in mobile ad-hoc networks

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.
