802.11-Based Multihop Ad Hoc Network Implementation

By far most of the experiments on ad hoc network research have been done by using simulators. Although easier than a real implementation, simulation can not yet reflect the real network environment entirely. Hence, in-depth research on ad hoc network requires a real implementation. To date, some Linux-based ad hoc network implementations have been proposed. In this paper, we present a multi-hop wireless ad hoc network implementation on Windows system based on 802.11 single-hop ad hoc mode. In the implementation we have adopted ad hoc on-demand distance vector (AODV) protocol as the routing protocol. In this paper, we first introduce the background, and then analyze the key implementation problems we have faced. Aiming at those key problems we propose a design framework based on NDIS intermediate driver and discuss some key techniques to solve them. Finally, some experiment results on our implementation was demonstrated.
