DESIGN FOR MOBILE NODE OF AD HOC NETWORKS BASED ON EMBEDDED ARM-LINUX

摘要

Heretofore, most of previous analyses in Mobile Ad Hoc Networks (MANETs) have been performed using simulators, which are largely different from the real MANET test-bed with the complicated and dynamic connectivity. In order to study the Ad Hoc network characteristics in the real environment, the paper presents a design method of mobile node specially for MANETs based on the embedded ARM-Linux. The classic protocol named Dynamic Source Routing (DSR) is transplanted into the embedded ARM-Linux platform. The investigated scenario involves a stationary testbed that includes ARM mobile nodes connected using IEEE 802.11 in the Ad-Hoc working mode. Finally, the performance of mobile nodes is examined. The experimental results show that mobile nodes can work efficiently and reliably, which realize the function of the Ad Hoc network successfully.
