Research On A Multi-domain Resource Allocation Model And Pricing Mechanisms For Wireless Ubiquitous Networks

With the explosive growth of the services and varieties of QoS requirements in wirelessnetworks, it is necessary taking the effective service customizing, resource scheduling and usermanagement into account in the commercialization development. The social attributes of thewireless networks keep growing so that the wireless networks become an important part not only inthe information infrastructure but also in the whole society. The model of the multi-domain resourceallocation with certain economic significance is realized for the wireless ubiquitous network, thuspromotes the innovation of the wireless services.First, the thesis focuses on the research of resource allocation for the real-time services, usingMIMO technology to make the use of the resource of the space domain, using adaptive modulationto allocate the resource of the power domain to enhance the spectrum efficiency, usingtwo-dimensional Markov chain to model the reliable/unreliable data receiving process duringadjacent scheduling frames, and using the effective bandwidth and effective capacity theories toallocate the resource of the spectrum domain so that the QoS assurance mechanism is considered.The simulations show the superiority of the performance of the proposed algorithm in the packetdelay and packet dropping ratio of the real-time services. Then, the thesis proposes aproduction-consumption model with some economic significance, explores the common pricingmechanism of the ubiquitous wireless network, and proposes the flat pricing based on the QoS leveland parameter-based QoS pricing. Last but not least, the thesis introduces the basic economicconcepts, such as utility, social welfare and user fairness, into the communication infrastructuretheories, gives out the quantizated forms of the formula, establishes a model of the resourceallocation baed on the maximization of the social welfare with the consideration of service, user andresource domain, and proposes the resource scheduling algorithm based on the flexible service. Thesimulation shows the superiority of the proposed algorithm compared to the traditional algorithm.
