Paper Abstract:
|
Mobile ad-hoc networks have become increasingly popular in the last years and promise a huge potential for the future. Ad-hoc networks allow users to communicate without a fixed network infrastructure, thus are interesting for many mobile communication scenarios. Multi-hop ad-hoc networks extend the communication range of individual nodes with the help of ad-hoc routing protocols. Many researchers focused on lower communication layers and developed several protocols in the past. In this paper, we want to abstract from the physical layer, the data link layer and routing issues and want to measure the quality of an ad-hoc network independently from network and hardware issues. For this, we first introduce a formal network model and a set of metrics. With the help of a simulation tool, we then measure the quality of ad-hoc networks in specific scenarios.
We especially want to discover the prerequisites for sufficient connectivity, stabil-ity and coverage. We call the number of nodes to form a reasonable network the critical mass. As a result of our simula-tions, we get a considerable high critical mass for realistic usage scenarios |
