Communication Network Resource Allocation Based On Network Pricing Strategy

With the increasingly amount and the heterogeneous nature of the network application, network resource such as bandwidth has becomes a kind of typical scare resource and requires careful allocation and control if optimal system performance and maximal user satisfaction are to be achieved.Approaches based on pricing theory can provide distributed solution for different customers, so they are very appropriate to deal with the complicated problems in communications networks. With the integration of Internet and wireless networks, the research on the network resource management based on economical models and game theory has experienced a remarkable development.The problems that can be investigated based on economic models include flow and congestion control, routing, access control, scheduling, network design and resource pricing, etc. At present, Internet is used by an increasingly growing and heterogeneous set of users. Many kinds of applications are based on a wide range of performance criteria.The dissertation studies the Internet resource management based on economic models and game theory, and the main research fileds include:1. At first, some research background about this thesis topic is introducted. We present the research status and the problems to be resolved about network resource allocation and quality of service. Then we give the research purpose and expound the necessity of introducing the economic theories. Finally, we summarize the contents and innovations of this paper.2. The status of the network economic models and pricing schemes are generally described at first. We present a pricing structure based on broker intergrating the pricing scheme into DiffServ network. Upon this platform, network service providers can freely choose the proper pricing scheme to guarantee their revenue and users' QoS. Finally, the network resource allocation modle is put forward which is based on the competition between the service poviders. We make a qualitative analysis about the relationship between price and capacity.3. A simple and efficient queue scheduling algorithm based on paris metro pricing(PMP)is presented which is for the DiffServ in the commercial network . Price is as one of the ways to differentiate the priority. This paper proves that the strict guarantee of delay and the optimal revenue can be obtained through updating weight and call admission control.4. A scheme of adaptive traffic distribution is presented which is for the flow contention in the Ad hoc network. In this paper, we define the flow utility based on the flow priority. Based on the Nash bargaining solutin and the shadow price of the microeconomic, the end-to-end optimal flow rate can be cooperate in distribute way during competing for the resources. At the same time, the QoS of flow with high priority can be guaranteed.5. In order to induct the nodes in multi-hop cellar networks to cooperate, we present a relay-degree-based incentive pricing scheme. The proposed scheme adjusts the price of compensation costs based on the importance of mobile nodes in the network topology. The result indicate that the propose scheme leads to increase service availability without additional costs.6. In the last chapter,we conclude the whole paper and point out the the succeeding works in the future researches.
