The most suitable technology is the emerging Ultra-wideband (UWB) technology in the frequency range from 3.1 to 10.6 GHz. It provides high data rates, robust radio channels, sufficient spectrum resources, worldwide usage' free of frequency licensing and a convenient spatial containment. The ECMA-368 standard is the first to describe a physical layer and Medium Access Control (MAC) layer definition for a high data rate UWB communication. An analysis of the protocol examines the behaviour in critical situations. In analytical and simulated computations the node density is investigated and a strict upper limit is defined. In the aircraft environment a high node density is expected; therefore techniques are presented to overcome this limitation. Simulations of the start-up time, the time shortly after the network has been powered, reveal a significant longer stabilisation time for networks with more than 40 nodes. The distributed beaconing algorithm with contraction mechanism requires several iterations to converge to a stable state. This convergence results in an exponential correlation with the number of neighbours. Other critical parameters being investigated are the expected throughput and influences of alien devices. With the identified limits of the communication protocol it was possible to develop new algorithms for resource management. An integer linear program calculate the access point positions and default channel allocations. These calculations are done during the design phase of the cabin and special attention is given to the unique features of the communication protocol that will have significant influence on the results. Later, during operation of the aircraft, a real-time algorithm dynamically calculates the resource reservation, depending on changes in the available spectrum, blocked or failed devices and traffic requirements. The algorithm is distributed to sustain communication even if the network is parted. In order to enable mobility in the aircraft, existing mobility protocols have been investigated and enhanced. The combination of Mobile IPv6 and Fast Handovers for Mobile IPv6 (FMIPv6) shows good results, but still lacks in non-interruptible communication for reactive handovers. Enhancements to FMIPv6 are presented that overcome this problem by defining backup access routers that receive duplicates of transmitted packets and will resend those packets in case of connection loss between the mobile node and the current access router. This approach is technology independent and can be used in the dual interface cabin concept to enable hot redundant transmissions over different technologies.
