In a mobile ad hoc network, difficulties exist in supporting address autoconfiguration and naming resolution due to the lack of centralized servers. This letter presents a novel approach, called name-based autoconfiguration (NBA), which uses host names to determine IP addresses and provides address autoconfiguration and name resolution as a single protocol.

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.

3세대 이동 통신망인 UMTS/GPRS에서 IP 기반의 서비스를 제공하기 위해서는 이동단말이 IP 주소를 할당 받고 이 주소를 통하여 데이터 패킷이 전송된다. 하지만 IPv4에서 인터넷 가입자의 폭발적인 증가로 인해 IP 주소 부족 문제를 예견하고 있다. UMTS/GPRS에 IP 주소가 획기적으로 증가하는 IPv6(Internet Protocol version 6) 적용이 필요하다. 본 논문에서는 UMTS/GPRS 망에서의 stateless autoconfiguration 절차를 설명하고 이동단말이 DHCPv6 서버와 연동하여 IP 주소를 할당하기 위한 stateful autoconfiguration 방법을 제안한다.

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 novel method to perform a quantitative analysis of message complexity and applies this method in comparing the message complexity among the mobile ad hoc network (MANET) address autoconfiguration protocols (AAPs). To obtain the upper bound of the message complexity of the protocols, the O-notation of a MANET group of N nodes has been applied. The message complexity of the single node joining case in Strong DAD, Weak DAD with proactive routing protocols (WDP), Weak DAD with on-demand routing protocols (WDO), and MANETconf has been derived as n(mO(N)+O(t)), n(O(N)+O(t)), n(O(N)+2O(t)), and nO((t+1)N)+O(N)+O(2) respectively. In order to verify the bounds, analytical simulations that quantify the message complexity of the address autoconfiguration process based on the different coflict probabilities are conducted.

A hybrid Ad-hoc network connected to the Internet needs an IP address configuration to communicate with the Internet. Most of proposed address autoconfiguration algorithms are node based. The node based address autoconfiguration algorithms waste bandwidth and consume much battery in mobile ad-hoc networks. In this paper, we propose the address allocation algorithm in hybrid Mobile ad-hoc network (MANET). The proposed algorithm reduces network traffic by transferring address configuration packet to the internet gateway by unicast method. Moreover, our IP address configuration algorithm also reduces battery consumption and address configuration time by decreasing number of configuration packets on internet gateway.

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.

For the auto-configuration of diverse hosts and automation of network management as many electronic machines and industrial components are becoming connected to Internet, it is possible to use autoconfiguration using DHCP and network management protocol such as SNMP, CMIP. But these technologies are not developed maturely and lack various standardizations yet because these are designed for restrictive purposes in the past. The new working group "Zeroconf" is made in IETF at March, 2000, it is aimed for making standards of autoconfiguration which is applied to impromptu ad-hoc networks in automobiles, trains, planes and home network or mobile networks. In this paper, we introduce the IPv6 based autoconfiguration technologies such as IP interface configuration, translation between host name and IP address, IP multicast address allocation and service discovery. Finally, trends of standardization in Zeroconf working group will be shown. be shown.

The concept of IPv6 stateless address autoconfiguration lends itself easily to mobile ad hoc networks. However, the Neighbor Discovery protocol (NDP)-based mechanism described in [1] does not fit well for the multi-link environments in the mobile ad hoc network. In this document, we extend the current SAA mechanism to be suitable for mobile ad hoc networks.

To connect a mobile ad hoc network (MANET) with an IP network and to carryout communication, ad hoc network node needs to be configured with unique IP adress. Dynamic host configuration protocol (DHCP) server autoconfigure nodes in wired networks. However, this cannot be applied to ad hoc network without introducing some changes in auto configuration mechanism, due to intrinsic properties (i.e., multi-hop, dynamic, and distributed nature) of the network. In this paper, we propose a scalable autoconfiguration scheme for MANETs with hierarchical topology consisting of leader and member nodes, by considering the global Internet connectivity with minimum overhead. In our proposed scheme, a joining node selects one of the pre-configured nodes for its duplicate address detection (DAD) operation. We reduce overhead and make our scheme scalable by eliminating the broadcast of DAD messages in the network. We also propose the group leader election algorithm, which takes into account the resources, density, and position information of a node to select a new leader. Our simulation results show that our proposed scheme is effective to reduce the overhead and is scalable. Also, it is shown that the proposed scheme provides an efficient method to heal the network after partitioning and merging by enhancing the role of bordering nodes in the group.
