Performance Evaluation of Interconnection Mechanisms for Ad Hoc Networks across Mobility Models

Abstract

There is being an on-going effort in the research community to efficiently interconnect Mobile Ad hoc Networks (MANET) to fixed ones like the Internet. Several approaches have been proposed within the MANET working group of the Internet Engineering Task Force (IETF), but there is still no clear evidence about which alternative is best suited for each mobility scenario, and how does mobility affect their performance. In this paper, we answer these questions through a simulation-based performance evaluation across mobility models. Our results show the performance trade-offs of existing proposals and the strong influence that the mobility pattern has on their behavior.
