Abstract [en]

Wireless ad-hoc networks have recently gained significant research attention due to their vast potential of applications in numerous fields. Multihop routing is a significantly important aspect which determines, to a large extend, the overall performance of the network. A number of routing protocols have been proposed for routing in wireless ad-hoc networks with focus on optimizing different aspects of the network routing. This report focuses on studying two popular protocols for wireless networks: Ad-hoc On Demand Distance Vector (AODV) and Optimized Link-State Routing (OLSR). The two protocols belong to different classes of routing categorization. AODV is a popular on-demand (reactive) routing protocol whereas the OLSR is a popular link-state based proactive routing protocol. The technical aspects of the two protocols shall be studied while highlighting the differences between the two and simulation based performance comparison of the two protocols shall be carried out under varying traffic and network conditions using the Network Simulator.

Abstract [sv]

This thesis is mainly divided into ten chapters. Chapter 1 introduces the topic with the detailed discussion of MANET. Chapter 2 presents the background of our work and types of wireless networks and some part of related work. Chapter 3 gives the theoretical background and concepts of the ad-hoc mobile network routing protocols i.e., reactive and proactive routing protocols. Chapter 4 presents the implementation details and the simulation modeling of ad-hoc network. Chapter 5 is about evaluation metrics: throughput, routing overhead, end-to-end delay, packet loss, packet delivery percentage. Chapter 6 presents the description and motivation about scenarios. Chapter 7 gives the theoretical background about the convergence and loop freeness of OLSR and AODV routing protocol. The analysis along with the simulation results of all the focused routing protocols presented in chapter 8. The conclusion and future work is presented in chapter 9, and chapter 10 presents the appendix.
