Temporal Evolution Of Network Topology And Its Applications In Mobile Networks

With the progress of information technology,we are now in a mobile network world,consisting of mobile telecommunication network,mobile Internet,mobile social network and mobile opportunistic network etc.These networks mentioned above are ubiquitous and their growth is off the charts.The research on the structure and function of network has become complicated because of the large scale of network,as well we the diversity and mobility of nodes in the real world.Therefore,the traditional methods of static topology analysis mainly focus on topological characteristics at a specific time,thus cannot depict the changing trend of network topology in the future and cannot reveal the evolving law of the network.According to the above problems,this paper conducts research works in the following two aspects:(1)Thorough research on mobile networks from the view of topological changing and temporal evolution has been conducted,focusing on community based topological evolution analysis method.A community based network evolution analysis model is proposed based on multiple time slices,and verified it in the real mobile data sets.(2)The link prediction in mobile network has been investigated.a link prediction method based on the proposed community evolving model is proposed.The proposed method fully integrates temporal and topological information of the network and has been successfully applied to mobile network dataset.
