  • Increase in the number of sensor nodes in sensor networks and sensor node to automatically assign addresses are needed. The method developed to address existing severe wasting, coordinators have all address information, each sensor node when addressing the shortcomings are a lot of traffic. In this paper, 6LoWPAN automatically from the sensor nodes capable of efficiently addressing Hop-Count based hierarchical address allocation algorithm is proposed. How to propose a hop-count of divided areas are separated, with no overlap and can be assigned a unique address, DAD(Duplicate Address Detection) reduced area. Perform DAD to reduce traffic, packet transmission in the IP header destination address, respectively, with a minimum 32-bit compression and packet transmission over a non-compression method to reduce the number of 11.1%.

  • Obtaining delivery addresses from calls is one of the most important processes in TV home shopping business. By automating this process, the operational efficiency of TV home shopping can be increased. In this paper, a method of recognizing and validating road name address, which is the address system of South Korea, from speech oriented text is proposed. The speech oriented text has three challenges. The first is that the numbers are represented in the form of pronunciation. The second is that the recorded address has noises that are made from repeated pronunciation of the same address, or unordered address. The third is that the readability of the resulted address. For resolving these problems, the proposed method enhances the existing address databases provided by the Korea Post and Ministry of the Interior and Safety. Various types of pronouncing address are added, and heuristic rules for dividing ambiguous pronunciations are employed. And the processed address is validated by checking the existence in the official address database. Even though, this proposed method is for the STT result of the address pronunciation, this also can be used for any 3rd party services that need to validate road name address. The proposed method works robustly on noises such as positions change or omission of elements.

  • A Mobile Ad hoc Network (MANET) is a group of independent mobile computing nodes that consist of a multi-hop wireless network without a central administration or any infrastructure. Every node that wants to join a MANET must obtain an address for communication. Having a centralized DHCP server that provides addresses to nodes, we can easily and automatically obtain addresses. However, a MANET lacks any fixed infrastructure such as a DHCP server. We therefore propose a distributed address autoconfiguration approach for a MANET using a reserved address and optimistic Duplicated Address Detection (DAD). The reserved address helps to reduce the allocation latency, and the optimistic DAD guarantees the uniqueness of addresses and lessens communication overhead. We then suggest methods of handling network partition and network merging situations, and go on to evaluate our approach through simulations. The simulation result shows that our scheme guarantees the uniqueness of allocated address and considerably improves allocation latency and communication overheads.

  • Address resolution protocol (ARP) is used for binding a logical address to a physical address in many network technologies. However, since ARP is an stateless protocol, it always abused for performing ARP-based attacks. Researchers presented many technologies to improve ARP protocol, but most of them require a high implementation cost or scarify the network performance for improving security of ARP protocol. In this paper, we present an address auto-resoultion (AAR) network system to neutralize the ARP-based attacks. The AAR turns off the communication function of ARP messages(e.g. request and reply), but does not disable the ARP table. In our system, the MAC address of destination was designed to be derived from destination IP address so that the ARP table can be managed statically without prior knowledge (e.g., IP and MAC address pairs). In general, the AAR is safe from the ARP-based attacks since it disables the ARP messages and saves network traffics due to so.

  • A modified driving waveform is proposed to improve the address discharge characteristics using wall charge on the common electrodes in plasma display panel. In the driving scheme of plasma display, after a reset period, the negative charge are accumulated on two front electrodes and positive wall charge are accumulated on the address electrode. As the address discharge during an address period is produced when the scan and address pulses are applied at the same time, negative charge on the scan electrodes and positive charge on the address electrodes are mainly used. On the other hand, as the voltage are only maintained without applying the waveform during an address period on the common electrodes, the wall charge is not used on the common electrodes. In this paper, the address discharge characteristics are investigated with changing pulse applying time and applied voltage amplitude on the common electrodes and consequently the producing time of an address discharge are shortened about 200 ns compared with the conventional driving waveform.

  • Due to the conversion from the existing address system to road name address system, the versatility of the road name address from the public and private sectors is increasing gradually. Therefor, the reliability of the road name address basic map, of the default data is also an urgent need, this means the accuracy of the data. But, road name address basic map is production time due to the use of different map accuracy is to fall, so is also the situation insufficient of utilization. This study Construction of identify each attempt by the road name address basic map and analysis the location accuracy of road name address basic map. As a result, the RMSE of cadastral survey results showed that appears lower than the RMSE of digital map survey results. The judgment can be utilized as the basis for the proposed improvements for the road name address basic map.

  • In this paper, we propose the address allocation algorithm in hybrid Mobile ad-hoc network (MANET). Most of proposed address autoconfiguration algorithms are node based. Node based address autoconfiguration algorithms are inefficient. Because the node based algorithms waste bandwidth and consume much battery in mobile ad-hoc networks. we present the address allocation algorithm using internet gateway based address autoconfiguration by modifing the IPv6 stateless address autoconfiguration protocol. We use the network simulator NS-2 in our experiments. The simulation result shows reducing network traffic and saving battery.

  • This paper proposes a multicast scheme over IEEE 802.16 networks which support multiple upper layer protocols such as ATM, IPv4 packets, IPv6 packets, IEEE 802.3 over IPv4 and so on. The multicast capabilities over IEEE 802.16 are important both control plane and data plane. The proposed multicast scheme can be divided into two types: direct mapping and indirect mapping. The direct mapping scheme is that layer 3 address is directly mapped into CID information which is used for connection identifier at IEEE 802.16 link layer. The indirect mapping scheme has two steps for mapping between layer 3 address and layer 2 CID. Firstly, a layer 3 address translates to Ethernet MAC address with group MAC address. Secondly, a group MAC address is mapped into CID. The mapping scheme depends on the upper layer protocols.
