摘要

In this paper, we present a feasible communication concept within the field of ambient networks and cognitive radios. The approach deals with the integration of different radio modules into an embedded communication platform. Basic idea is the simultaneous coexistence of multiple independent network interfaces, which allows us to combine the advantages of different communication technologies. At the same time we bypass the disadvantages of one single radio standard with its application specific design limitations. The result is a lightweight, radio standard spanning communication system, specially in the field of mobile ad hoc networks. The approach enables interesting new ways to create a reliable, heterogeneous network infrastructure. To avoid the influences of interferences in the topology, an observer unit identifies an increasing interference behaviour based on parameters like the packet loss rate, packet transmission time or fluctuations of the signal quality. With this knowledge base, we are able to adapt the transmission technology dynamically. Thus, the system takes an active influence on the local interference level in the network. Unlike other related research projects, this concept requires no special hardware devices and no complex software architecture. Instead, our approach focuses on standardised, low cost hardware components to realise an embedded communication platform. The presented paper analyses the feasibility with application-specific simulations and evaluate the results based on real world measurements with a designed prototype platform.
