Actual research projects in the field of wireless communication systems focus on distributed, heterogeneous architectures for advanced Sensor-Actor-NETworks (SANETs). Each subsystem provides specific capabilities for measuring or manipulating its environment. At the same time, a huge amount of sensor, status and control data has to be transmitted over different network interfaces and communication standards. During the runtime, the number and the quality of communication channels is changing dynamically. Especially in wireless multi-hop scenarios with several radio standards, the maintenance and the balancing of stable communication paths is critical. In this paper, the authors present a cross-layer resource leveling approach in the domain of heterogeneous SANET environments.
