Abstract:

In this paper we will basically study that how the problem of efficient multi hop forwarding of packets can be done in ad hoc networks destined for a gateway providing Internet connectivity. Mobile ad hoc networks have become a major component of the future network development due to their ease of deployment, self-configurability, flexibility and between MANETs and existing IP networks. Indistinct address and routing spaces are hard to integrate. In this paper the AODV reactive routing protocol is extended to support the communication between independence on any existing network infrastructure. So it is able in finding ways to efficiently interconnect them with the Internet. In fact such interconnections are not very easy due to differences in mobility, addressing and routing the MANET and the Internet. We have carried out a systematic simulation based performance evaluation of the different gateway discovery approaches using NS2 under different network scenarios.. On the study of various proposals for MANET-Internet connection we found that many of them are lacking in robustness and in flexibility. For example, many solutions do not consider the presence of multiple gateways, and in such scenarios they either fail, or are less efficient due to the lack of multi-homing capabilities. For an efficient Internet Connectivity in Mobile ad hoc networks, multiple gateways, potentially multi homing and proper hand-over need to be supported. We compare two forwarding strategies; default routes and tunneling to gateways. We find that tunneling is more efficient and flexible in compare to default routes.
