移动机会网络中的大数据路由理论和方法及应用基础研究

This project aims to study the issue of big data routing in mobile opportunistic networks. Firstly,we will break through the traditional idea of using static graph theory to study the problem of data routing in networks, with the modeling of the topology structure dynamic evolution of mobile opportunistic network as our study starting point, we propose a spacial-temporal graph model of the topology structure dynamic evolution of mobile opportunistic networks from the unified modeling perspective of time and space, and our purpose is to use the spacial-temporal graph model to precisely describe the new data routing scheme of storage-carry-forward in mobile opportunistic networks. Secondly，we will propose a new big data block routing method to improve the big data routing efficiency in mobile opportunistic networks. Thirdly, we will study the uncertainty and the time series characteristics of single hop decision of data routing in mobile opportunistic networks,and propose the uncertain decision model of data routing path selection for mobile opportunistic networks based on the Markov decision theory. Fourthly, considering the movement, residual energy of nodes and the reliability of wireless links between nodes, and using the unsupervised reinforcement learning method,we will design a distributed adaptive efficient decision algorithm for data routing path selection in mobile opportunistic networks. Finally, with the big data routing in mobile learning opportunistic networks as the background, we will carry out the application research. Our ultimate goal is to propose the new theory and method for the big data routing in mobile opportunistic networks. Thus, this project has important theoretical significance and wide application prospect.
