A wireless ad-hoc network: Design and performance evaluation of dynamic routing model

This paper describes the identification of potential problems with ad hoc routing protocol that contribute to the overall performance. Another major factor that contributes to routing protocol performance is when wireless nodes move out of coverage area of the other nodes and thus lose connection, or the opposite, where other wireless nodes join the network while on the move and require a dynamic route to a destination; this is defined as the mobility factor. The multimedia model shows how well the routing protocol can handle real-world traffic and guarantee Quality of Service, QoS, for this type of data. The circular model attempts to address for potential problems with ad-hoc routing where there is only one destination node. Lastly, the dynamic model attempts to address problems with an extremely dynamic topology where nodes leave and join the network continually, putting extreme strain on the routing protocol, and network overheads. The main objectives of this project were to investigate these models and appraise their performance after implementation using network simulator, ns-2, and investigate which models work well in which situations.
