As one of global leading operators in fiber-to-the-x rollout, KT is preparing for access network evolution, mainly based on 10G-EPON technology. In this paper, we will explain technical issues in achieving seamless migration from 1G-EPON network, and how we are to resolve them, reusing most of existing infrastructure.
In wireless multihop network, the inter-hop interference (IHI) is a major factor to deteriorate the end-to-end performances of multihop link. In this paper, we proposed a joint radio resource management with respect to scheduling and power control in order to mitigate the IHI and maximize the resource utilization and the end-to-end rate in the wireless multihop networks. The scheduling algorithm decides...
Several studies for survivability in MANET has been done, but there should be more considerations such as multichannel environment, tactical environment, and link failures. In this paper, we define survivability of tactical networks based on connectivity with multichannel environment and propose a method of measuring survivability of a network. We proposed a survivability measure scheme which calculates...
In tactical network OTM (on-the-move) environments, tactical nodes should overcome potential disadvantages such as harsh propagation channels and interference, and communication breakdown due to frequent and rapid changes in the network topology without centralized control AP such as immobile base stations as in common wireless networks. In this paper, we propose a group mobility model associated...
