| Research Abstract |
Research on information transfer in challenged networks was conducted. We developed a buffer management scheme in sparsely populated mobile ad hocnetworks, aiming to maximize the delivery ratio and to minimize the mean delivery delay.We also developed a method of finding relay nodes so as to minimize the mean deliverydelay, which utilizes local information only available at each node. We also developedsystem parameter optimization methods for layered 3D underwater sensor networks withsingle-copy routing and epidemic routing. Furthermore, we developed methods of findingan optimal visiting order of clusters and grouping clusters in ferry-assisted delay tolerantnetworks in order to minimize the mean delivery delay.
