Computing devices are commonly equipped with multiple transport technologies such as IrDA, Bluetooth and WiFi. Transport switching technologies, such as Quality of Transport (QoT), take advantage of this heterogeneity to keep network sessions active as users move in and out of range of various transports or as the networking environment changes. During an active session, the goal is to keep the device connected over the best transport currently available. To accomplish that, this thesis introduces a two-phase decision making protocol. In phase one, intra-device prioritization, users indicate the relative importance of criteria such as speed, power, service charge, or signal range through a comprehensive user interface. QoT-enabled devices process this information with the prioritized soft constraint satisfaction (PSCS) scoring function to ascertain the transport that best meets the user's needs. The second phase, inter-device negotiation, facilitates two QoT-enabled devices in agreeing to a unified selection of the best transport. This phase uses a modified version of the PSCS scoring function based on the preferences of both users. Additionally, devices may utilize multiple transports simultaneously to more accurately meet user demands. The PSCS scoring function considers pairs of transports and calculates the ratio that will yield the desired performance. Another set of functions, also presented in this thesis, is then used to accomplish the desired performance level despite the potential introduction of additional overhead.

Computing devices are commonly equipped with multiple transport technologies such as IrDA, Bluetooth and WiFi. Transport switching technologies, such as Quality of Transport (QoT), take advantage of this heterogeneity to keep network sessions active as users move in and out of range of various transports or as the networking environment changes. Autonomous transport switching technologies rely on information regarding current network status and the ambient wireless environment in order to make intelligent decisions. This thesis proposes Brand X, a cross-layer architecture designed for a QoT environment to provide timely and accurate environment information in order to facilitate autonomous transport switching. This thesis also presents a performance analysis of network protocol stack latency in a QoT environment considering the various cross-layer mechanisms utilized in Brand X and other architectures.

The thesis is concerning with the road transport of goods under controlled temperature. Under such goods we mean foodstuffs. The aim of the thesis is to describe the issue of road transport of foodstuffs on the whole logistic chain using the production of Danone company as an example for illustration.

Annotation: This thesis deals with the transport service in the South Bohemia Region municipalities. It evaluates the transport service quality from the viewpoint of public transport. The methodical part comes out of the theoretical part and it focuses on the number of links of particular municipality and its centre. Both road and train links were analyzed on the basis of the schedules in various time periods. The supplementary part is occupied with the municipalities? transport location and their relationship to the transport service. The final part contains the results evaluation and the synthesis of given problematics. The transport-geographical characteristic of chosen area, the map attachments and the table attachment containing data from the research are also a part of the thesis.
