Abstract [en]

Mobile ad hoc networking allows nodes to form temporary networks and communicate beyond transmitter range by supporting multihop communication through IP routing. Routing in such ten reactive, i.e., performed on-demand, as opposed to Internet routing that is proactive. As ad hoc networks are formed on a temporary basis, no assumptions are made about the IP addresses of the participating nodes; nodes may use any address. Because of these characteristics, it is not straightforward to connect an ad hoc network to the Internet. In this Master's thesis we have studied how an ad hoc network, in which on-demand routing is used and where nodes with arbitrary IP addresses may appear, can be connected to the Internet. Various ways of adapting Mobile IP to such an ad hoc network have also been explored. All this has resulted in the MIPMANET proposal.

MIPMANET provides Internet access by using Mobile IP with foreign agent care-of addresses and reverse tunneling. By using Mobile IP, nodes are routable regardless of which network they are currently located in and by using reverse tunneling the requirements on the ad hoc routing protocol in use are kept at a minimum. Also, by using an interworking unit between the foreign agent and the ad hoc network no modifications to Mobile IP have to be made outside of the ad hoc network. MIPMANET also provides transparent interaction between Mobile IP and the ad hoc routing protocol.

To allow analysis of the MIPMANET proposal, we have implemented it in Network Simulator 2 (ns). The Ad hoc On-demand Distance Vector (AODV) Routing protocol has been used for routing within the ad hoc network. To illustrate the effects of different design choices and to form the basis of future evaluations, we have also performed some simulations. These simulations show that the ability to choose the closest gateway to the Internet is highly valuable.
