Research And Implementation Of Routing Protocols For Wireless Ad-Hoc Network

In recent years,we have witnessed a tremendous inflation in the world of mobile computing.Due to the increase of low-cost and widely available wireless devices,Ad-hoc networks have now become one of the most vibrant and active field of communication and networks and it has captured an important part of the interest of researchers.Mobile Ad-hoc Network(MANET)is an infrastructure-less mobile wireless communication system,meaning that MANET nodes are able to function both as an end system and also as a router to forward data packets.These nodes are free to move about and change position frequently without a centralized control mechanism.They forward data packets from one node to another in the form of hops,hence the name “multi-hop wireless network”.Just like with other wireless network,routing protocols are the primary strategy to its design.Route discovery and packet forwarding operations within a network need an efficient routing protocol.The main method for evaluating the performance of MANETs routing protocols is simulation.However,once simulations have drawn results and conclusions,real-world implementations are then carried out.The main objective of this thesis is to implement an AODV(Ad-hoc On-Demand Distance Vector)prototype router on the three different processors(x86,MIPS and ARM).I have chosen the Uppsala University's AODV(AODV-UU)and FB-AODV(Flow-Based)implementations as the baselines for the research.This paper describes the basic characteristics and key techniques of Ad-hoc networks compared to other mobile communication systems.It also introduces and focuses on the AODV routing protocol,and more importantly it gives a step-by-step procedure on how the AODV router implementations are done.Lastly,once the routers are successfully implemented,tests will be conducted to test the functionalities and performances of the router prototypes.
