  • An address is sub-spatial data representing a location, and identifies the place in which a resident's life is based. The Korean address system has changed from an area-based address system to the Road Name Address System in 2014 to solve the problems of the area-based address system and to accept the international address standards. Although the Road Name Address System is continually being modified and implemented it limitations. Therefore, the purpose of this study is to resolve these limitations and to analyze and redefine the Road Name Address System of Korea to implement the street-based address system. To understand the address, we define the components of the address system and analyze the Korean Road Name Address System based on each component to derive the limit. To resolve the limitations of the Road Name Address System and to implement the street-based address system, the Road Name Address System is redefined according to three aspects. Finally, we evaluate the usability of the Road Name Address System proposed in this study through address based geocoding.

  • It is known that the address discharge delay time during an address period strongly depends on the wall charge leakage. It was observed that the wall charge leakage during an address period is related to both the address width and the ambient temperature. Accordingly, the effects of address electrode width on the address discharge and wall voltage variation during an address period were examined under variable temperatures.

  • The Internet has been growing at unprecedented rates. The problem of an address shortage could act as a barrier on this growth. In principle, a new Internet standard, IPv6 solves the problem of the address shortage because it has a very large address space. But IPv6 is not yet compatible with the IPv4 and during the IPv4-to-IPv6 transition period IPv4 address will continue to be in demand. Thus for quite some time, the problem of IP address shortage will persist. To solve the problem, we propose the mechanism of secure IP address trading. This mechanism is based on the Resource PKI (RPKI). The RPKI is the working item of IETF. This proposed mechanism maximizes the trust of IP address trading using RPKI.

  • An advantage of the mobile ad hoc network (MANET) is that mobile nodes can self-organize the network topology without the help of network infrastructure. However, for the perfect self-organization of the MANET, each mobile node needs to self-configure its address. Even though a mobile node configures a unique address during the booting time, its address may conflict with nodes in other MANETs since MANETs containing the same address can be merged. The address autoconfiguration protocol implemented in this work consists of the strong DAD (Duplicate Address Detection) and the weak DAD. A unique address of a node is assigned by the strong DAD during the booting time and the weak DAD is used to detect address conflict and resolve address conflict during the ad hoc routing. In this work, we have implemented address autoconfiguration in the IPv6-based MANET using AODV as the routing protocol. We describe how the IPv6 address autoconfiguration is implemented and verify our implementation by showing the test scenarios on our testbed.

  • The address discharge characteristics by the various scan-low and common-bias voltages are investigated based on measured address discharge time lags and $V_t$ close-curve analysis. The scan-low voltages are changed under the same voltage difference between the X and Y electrodes during an address period. As the voltage difference between the scan and address electrodes is increased during an address period, the address discharge time lag is shortened but the background luminance is increased. It is found that the improved address discharge characteristics is caused by the effect of the higher external applied voltage during an address period than the accumulated wall charges during a reset period and the high background luminance can be prevented by applying an address-bias voltage during a rising-ramp period and low reset voltage.

  • We introduce two distributed IP address auto-configuration mechanisms for mobile ad hoc networks. RADA (Random ADdress Allocation) is based on random IP address selection, while LiA (Linear Address Allocation) assigns new addresses sequentially, using the current maximum IP address. An improved version of LiA, hewn as LiACR (Linear Address Allocation with Collision Resolution) further reduces the control overhead. Simulation results show that, when many nodes join a network during a short period, RADA assigns addresses more quickly than LiA and LiACR. However, RADA uses the address space less efficiently, due to its random allocation of IP addresses. Hence, RADA is particularly useful in battlefield scenarios or rescue operations where fast setup is needed, while LiA and LiACR are more suitable for ad hoc networks that are moderate, confined and subject to some form of governance control, such as that orchestrated by a wireless service provider.

  • In order to automate the process of mail sorting by delivery sequence, it is necessary to prepare a postal address database and to interpret written addresses on the mail-pieces with the database and OCR technology. The address database is a critical factor of automation and informatization of postal service since it could be used not only in address recognition but also in various mail processing. In this study, we design the schema of postal address database, design the postal address file based on it and explain the method of address interpretation and retrieval using it. We analyze infonnation requirements for transformation of postal address into the standardized format and consider them in the process of design. The postal address file can be used by address matching or retrieval system as well as by Hangul address recognition system for automation of delivery sequence mail-sorting.

  • The IPv6 protocol provides the method to automatically generate an address of a node without additional operations of administrators, Before the generated address is used, the duplicate address detection (DAD) mechanism is required in order to verify the address. However, during the process of verification of the address, it is possible for a malicious node to send a message with the address which is identical with the generated address, so the address can be considered as previously used one; although the node properly generates an address, the address cannot be used. In this paper, we present a strong scheme to perform the DAD mechanism based on hash functions in IPv6 networks. Using this scheme, many nodes, which frequently join or separate from wireless networks in public domains like airports, terminals, and conference rooms, can effectively generate and verify an address more than the secure neighbor discovery (SEND) mechanism.

  • The MANET(Mobile Ad Hoc Network) is an independent network that is oranized by only Mobile Hosts. MANET guarantees the mobility of the node and does not need a backbone network or a base station. Recently, there is a strong demand to connect MANET to the Internet. For the interconnection between MANET and Internet, Mobile hosts of MANET must have global IP address. The well known scheme of the address configuration for MANET is SAA(Stateless Address Autoconfiguration). SAA configurated IP address by node itself. The advantage of SAA is not requiring any server for address configuration. However the SAA has problems of unstable and inefficient interconnection on the AD Hoc Network. To solve this problem we propose a method that assigns an IPv6 Global address to the node through the Internet Gateway. The format of assigned IPv6 address is also defined. The simulation result demonstrates that the proposed method can support the host for fast getting of global IPv6 Address and Mobile IPv6 efficiently.

  • I must receive node discernment address for communication between node that participate to network in MANETs(Mobile Ad-hoc Networks). Address is created by node confidence or different node. I achieve address redundancy check (Duplicate Address Detection) to examine whether this address is available unique address. However, this method happens problem that MANETs' extensity drops. This paper can manage by group unit binding transfer nodes to group in MANETs. I suggest method that apply special quality of cluster that exchange subordinate decrease and mobility government official of control message are easy in address assignment protocol minimize time required in redundancy check and solves extensity problem. Method that propose in this paper shows excellent performance according to node number increase than wave and MANETConf [2] through simulation.
