The goal of the thesis is to design the star-based mesh topology by introducing multiple pan-coordinators (hub/switches) under a multipath-fading environment and to improve the data transaction rate of a network which usually gets worst when there is a single pan-coordinator for synchronization of devices in conventional mesh topology; also reduce the hop-count as least as possible. Most of the work has been done on NS-2 network simulator; therefore the research model which has been used here is a simulation model. Altogether 3 simulations have been done. The first scenario is done on a simplest mesh network with a single coordinator and a radio propagation model which has been used is two-ray ground reflection model. The second scenario simulation is similar to the first scenario but in-order to provide multi-path signal fading and highly congested environment the propagation model which has been used this time is shadowing model. The final simulation which has been done is of multiple-star based mesh topology it also uses the similar radio propagation model which has been defined for second scenario. An intensive performance measurement of all the three simulations has been done in terms of transactions made per-second, packet drop rate along with an analysis of packet drop. An hop-count is also measured between star and mesh topology. For multiple star based mesh topology it can be assumed if multiple stars with a routing capability can be used then nodes in a network will be synchronized or re-synchronized with least number of hops in the congested network with a near-by pan-coordinator (hub/switch). One of the major applications of this topology can be automobile manufacturing industry where alot of machines are installed in a congested network and monitoring of every area is mandatory for swift production.

- Criteria for a definition of a full function joint venture in the decision-making of the Commission This thesis focuses on the progress in the Commission's approach towards full functioning joint ventures and on criteria for their determination. A full functioning joint venture is a joint venture type that fulfils criteria given by the Commission of the European Union - joint control and full functioning, that consists of functional autonomy, lasting basis and resources. The first, inductive part provides a short joint venture typology and explains ways by which the European law regulates those concentrations. The second part of the thesis serves as a necessary historic excursus to the progress in the European Union Commission's view on cooperative and concentrative concentrations and its goal is to clarify on the basis of which factors and how this approach has developed from 1968 to the present. The third, main, part of the thesis is an analysis of particular full functioning joint venture determination criteria. Each criterion is analysed separately with regards to specialised publications, regulations, reports and directives, especially by analysing European Union Commission's rulings, as the result of the application of the approach towards full functioning joint ventures by the European...
