A Study Of Traffic Model And Queuing Schedule Algorithm Based On The Convergence Of WSN And Mobile Network

With the rapid development of communication technology, there are growing demands for the control and management of remote machines and the obtaining and processing of information. Currently, the heterogeneous networks based on the convergence of the WSN and mobile network (hereinafter referred to as the heterogeneous network) become to be the most practical and convenient way to provide communication solutions that meet those demands. As the peripheral cognitive network, WSN provides effective reliable and real-time front-end data, while mobile network makes WSN more administrable and more easily to be operated and maintained. There has been the consensus from experts that with the mutual complement and common development, these two networks are tending to be the next Ambient Ubiquity Network.Through the study of WSN and traditional mobile network research, this paper points out that in the process of these tow networks' convergence, the generation and transfer of effective data, which on convergence parts of the heterogeneous network, presents features of locality, periodicity, randomness and suddenness. For above-mentioned features of the heterogeneous network, the third chapter of this paper provides the detailed analysis on functions and features of the traditional IP network traffic model; moreover, it presents a new traffic model that matches new features of the heterogeneous network.With the help of queuing theory as the mathematical tools and theoretical basis and according to the multi-service capability of SINK node in the heterogeneous network, the forth chapter analyses performance parameters of multiple-windows service queuing system and compares performance parameters of multiple-path multiple-window service system and single-path multiple-windows service system. Finally, it makes a conclusion that latter's performance parameter are superior to the former'sOn the practical analysis of data length and delay time in SINK node presented in the forth chapter and on the theoretical basis of game theory, the fifth chapter constructs a SINK node's connection scheduling game theoretical model. Furthermore, this part provides the theoretical analysis and proof of the existence of Nash Equilibrium in this game theoretical model and then, above-mentioned conclusions are validated through the computer simulation.Based on above studies, this paper point out a practical direction for the consequent research on the traffic model and queuing schedule algorithm of SINK node, which plays a key role of heterogeneous network.
