Interactions between TCP, UDP and Routing Protocols in Wireless Multi-hop Ad hoc Networks
2005 (English)In: Proceedings of the 1st IEEE ICPS Workshop on Multi-hop Ad hoc Networks: from theory to reality (REALMAN 2005), 2005Conference paper (Refereed)
The achieved throughput in an ad hoc network is affected by many factors, including radio interference between hops, the ability of the routing protocol to react on topology changes and a complex interaction between the application and underlying protocols. This paper studies experimentally the impact of these factors on UDP and TCP throughput. Furthermore, when both TCP and UDP share some hops in an ad hoc network there is a complex interaction between the transport protocols as well as with the routing protocol. Our results show that this interaction results in significant UDP jitter, instable routes and significantly lower TCP throughput. We use a controlled real testbed for the experiments and a graphical tool that captures the interactions.
