Several IP autoconfiguration techniques for MANET have been proposed by this time. But most of them concentrate on dealing with address duplication, so they have problems with latency and inefficient address space utilization. In this paper, we proposed a new IP autoconfiguration technique, namely Relational MANET Autoconfiguration Protocol(RMAP). This technique distributes IP addresses effectively by exchanging messages and recovers IP addresses by applying parent-child relationship. Simulation experiments are conducted to demonstrate the enhancement of the proposed algorithm over other known algorithms regarding latency, uniform distribution, and IP address recovery ratio.

As it becomes increasingly important that Internet access is available anywhere at any time, providing MANET (Mobile Ad-Hoc Network) with the Internet access attracts more attention. The existing DHCP (Dynamic Host Configuration Protocol) address configuration schemes require message exchanges between MANET nodes and the DHCP server through multi-hop routes. Messages can be easily dropped in the wireless multi-hop communication environment and the address configuration may be instable and need long delay. In this paper, we propose a new address configuration scheme using the concept of address pool allocation. In the proposed scheme, the DHCP server assigns a part of its address pool to a node instead of a single address and the node can assign a part of its own address pool to its neighbor nodes. Through simulation studies, we show that our scheme yields about 77% of the address configuration delay and 61% of the control message overhead of the existing DHCP based mechanism.

We can categorize the network address allocation mechanism into two types. One is to assign a unique network address using the address allocation server and the other is to make a random address by itself and process the DAD(Duplicate Address Detection) procedure. In this paper we suggest a new address allocation mechanism based on the signal strength for the PLC-based home network. As the combined mechanism of two types this mechanism allocates a unique address for the new node from one of the existing nodes with the simple equation and with the priority based on the signal strength from the new node to the existing nodes. We can use this mechanism for the self-healing function when the packet from the source node may not be delivered to the destination node directly. We developed the simulator for our mechanism using the C# programming and verified the network address assigned uniquely based on the signal strength.

There There is a difference in terms of administrative power in that the address of things are not an address under Public Act. In terms of location expression, it is possible to express the location more flexibly and in more detail than the road name address, so it should be improved so that it can be assigned and managed in an appropriate location, so that the location of the entire territory can be expressed together with the road name address. As a result of the comparison between the road name address and the address of things based on the analysis results of related laws such as the existing Road Name Address Act, the Building Act, and the Regulations on the Preparation and Management of Basic Address Information, it was confirmed that there are fundamental limitations of the address of things system. Accordingly, this study attempted to suggest ways to improve the address of thing system by broadly dividing it into the legal aspect and the addressable object aspect. From the legal point of view, firstly, it is necessary to improve the upper and lower level laws by unification together with a clear definition of the term subject of addressable object; secondly, according to the Building Act, facilities that are not used for residence among buildings must be given an address of thing; and thirdly, it is necessary to make it easy to use and link with heterogeneous public data by classifying the registration items of the basic address information map by type of geographical feature to be assigned an address. From the point of view of addressability, firstly, it must be given to all facilities in the relevant category so that it can be recognised that all specific facilities have object addresses, and secondly, it is necessary to be able to address the address of things to places that are used by many, even if there are no facilities.

The referents of internet addresses are no longer limited to web sites. A new address service by the international organization for the internet address (ICANN) introduces an open space for the TLD (Top Level Domain) strings so that each service, content, product, and other linguistic expressions may be allowed. The open TLD addresses are more suitable for representing the address of service units, contents, or products. In this paper, as an alternative to static Internet address service to return a consistent mapping result regardless of a user-specific different requirements, we design a dynamic internet address mapping model that returns mapping result to suit user particular requirements. In addition, we propose a method for implementing a internet address service without any changes in the existing domain protocols. It may implement a dynamic internet address by attaching to a encoded user's metadata and environment data within a internet address representation, and adding the module for dynamic mapping to the name servers. Through this proposal, trying to expand the functions of internet address, it is expected to be able to provide customized informaiton retrieval services for each user by using just internet address.

It is well known that the current wireless sensor networks addressing methods do not work efficiently in networks more than a few hundred nodes. A standard protocol in ZigBee-Standard feature in ZigBee 2007 gives balanced tree based address assignment method with distributed manner. However, it was limited to cover less than hundreds of sensor nodes due to the wasteful use of available address space, because composed sensor networks usually make an unbalanced tree topology in the real deployment. In this paper, we proposed the hierarchical cluster tree based address assignment method to support large and scalable networks. This method provides unique address for each node with distributed manner and supports hierarchical cluster tree on-demand. Simulation results show that the proposed method reduces orphan nodes due to the address exhaustion and supports larger network with limited address space compared with the ZigBee distributed address assignment method defined in ZigBee-Standard feature in ZigBee 2007.

이 논문은 TCP/IP 기반 지역 망 내에서 개인용 컴퓨터의 사용에 있어 인터넷 프로토콜의 주소 충돌 해결 방법에 대하여 연구하였다. 현재 컴퓨터의 수는 계속해서 늘고 있지만 사용자는 IP 주소에 대한 지식이 없음으로 인해 고의나 실수로 자신의 것이 아닌 다른 사람의 IP 주소를 사용할 수 있고, 이로 인해 원래 사용자가 네트웍을 사용할 수 없게 된다. 본 논문은 사전에 지역 망 내의 관리 대상 컴퓨터들의 주소정보를 DNS 서버상에서 수집하여 현재 사용하는 주소 정보가 저장된 정보가 같은 지를 검사하는 방법으로 IP 조소 충돌 검출 방법을 제시하였다.

본 논문에서는 자율-구성 차량 네트워크 환경에서 차량 내 정의된 서비스를 정의하기 위한 새로운 주소 체계를 제안한다. 기존 IPv6 기반 주소 설정 기법은 차량 내에 서비스를 정의할 수 있는 필드가 존재하지 않는다. 따라서 자율-구성 차량 네트워크 구축 시 기존 방법에 한계점이 있다. 따라서 본 논문에서는 NAT 개념을 적용하여 만들어진 IPv6 기반의 ULA 주소 체계를 활용하여 차량 내 서비스를 식별할 수 있는 주소 체계를 제안한다.

새로운 DEC Alpha, MINPS R40001[1], PowerPC등과 같은 64-bit 마이크로프로세서는 운영체제와 응용프로그램에 매우 광활한 64-bit 주소공간(wide address system)을 제공한다. 64-bit 주소공간은 중소규모 분산 컴퓨터 시스템의 모든 데이터를 포함할 수 있는 크기이다. 이 64-bit 주소공간은 32-bit 주소공간과 다른 방법으로 활용하는 것을 가능하게 해주었다. 지금까지의 시스템과는 달리 WAS(wide address system)에서는 모든 프로세서들이 하나의 주소공간을 공유함으로서 프로세서간 자료의 공유 및 통신이 간편하게 이루어 질 수 있다. 공유된 광활한 64-bit 주소공간의 상용방안은 WAS 시스템 연구에서 매우 중요하다. 본 논문에서는 WAS 시스템의 보다 구현하기 쉬운 64-bit 주소공간의 설계에 대해서 제안한다.

낸드 플래시 메모리는 하드 디스크와는 다른 여러가지 특성 때문에 논리 주소를 불러 주소를 변환해 주는 주소 변환 계층(FTL)이 필요하다. 최근에 고성능의 저장 장치를 제공하기 위해서 페이지 수준의 주소 변환 기법이 많이 사용되고 있는 데, 이 기법은 매핑 정보가 너무 커서 메모리에서 매핑 정보를 관리하기에는 힘들다는 문제와 데이터의 접근 지역성을 잘 활용하지 못하는 문제가 있다. 본 논문에서는 스토리지의 주소 공간을 유닛이라는 단위로 분리하여 페이지 수준의 주소변환을 사용함으로써 매핑 정보를 크기를 줄이고 또한 접근 지역성을 활용하여 가비지 컬렉션 오버해드를 줄이는 유닛 레벨 주소 변환 기법을 제시한다. 실험결과 제시한 기법은 페이지 매핑 기법보다 랜덤 접근 패턴에서 가비지 컬렉션 오버해드를 40% 감소시켰으며 매핑 데이터 량도 38% 감소시켰다.
