Auto-Configuration Protocols in Mobile Ad Hoc Networks

The TCP/IP protocol allows the different nodes in a network to communicate by associating a different IP address to each node. In wired or wireless networks with infrastructure, we have a server or node acting as such which correctly assigns IP addresses, but in mobile ad hoc networks there is no such centralized entity capable of carrying out this function. Therefore, a protocol is needed to perform the network configuration automatically and in a dynamic way, which will use all nodes in the network (or part thereof) as if they were servers that manage IP addresses. This article reviews the major proposed auto-configuration protocols for mobile ad hoc networks, with particular emphasis on one of the most recent: D2HCP. This work also includes a comparison of auto-configuration protocols for mobile ad hoc networks by specifying the most relevant metrics, such as a guarantee of uniqueness, overhead, latency, dependency on the routing protocol and uniformity

Towards establishing trust in manet:An integrated approach for auto-configuration,Authentication and certification

In this paper, we discuss open issues regarding certification, auto-configuration and authentication of routing messages for mobile ad-hoc networks (MANET). We describe and discuss existing models for these operations and highlight their specific problems. Considering routing protocols usage, we propose new solutions based on protocol modifications and distributed certifications that can be integrated to establish trust relationships for MANET operation and utilizatio

Design and Implementation of ID Based MANET Autoconfiguration Protocol

Auto-configuration protocols are used for assignment of unique IP addresses to nodes in Mobile ad hoc networks. Without the assignment of unique IP addresses, service provisioning between the nodes is not possible. Such protocols use various heuristics to ensure the uniqueness in IP address assignment; such aspects increase the overall complexity in MANET system design. Moreover the overriding role of IP address as an ID in Application layer and Locator in routing space is a bottleneck in future wireless network (FWN) design. Contemporary FWN research is focusing on ID/Locator split concept designs. In this paper we propose an ID/Locator based architecture for MANETs which also solves               auto-configuration requirements for MANETs. Our proposed architecture is an adaptation from available ID/Locator split concepts for infrastructure oriented networks for usage in MANET context. The designed protocol uses identifiers for node identification, node discovery and traffic flow between end points. The protocol support provision for running contemporary IP oriented services. We have also verified various use cases of our proposed protocol through Linux based implementation

E-D2HCP: enhanced distributed dynamic host configuration protocol

Mobile Ad Hoc Networks (MANETs) consist of mobile nodes equipped with wireless devices. They do not need any kind of pre-existent infrastructure and are about self-managed networks. MANETs enable communication between mobile nodes without direct links and across multihop paths. To ensure correct operation of the routing protocols, MANETs, have to assign unique IP addresses to the MANET devices. Furthermore, the address assignment is an important issue when dealing with MANET networks because the traditional approaches are not applicable without some changes, having to provide new protocols for the address auto-configuration. These schemes must take into account the properties of MANETs such as dynamic topology, limited resources or lack of infrastructure. In this paper, we propose a stateful scheme for dynamic allocation of IP addresses in MANETs entitled Extended Distributed Dynamic Host Configuration Protocol because it is based on a previous piece of work (D2CHP). This extension includes the network merging not covered by its predecessor. Simulation results show that the new protocol also improves D2HCP functionality in areas such as fault tolerance, concurrency and latency.Sección Deptal. de Sistemas Informáticos y ComputaciónFac. de Ciencias MatemáticasTRUEAgencia Espanola de Cooperacion Internacional para el Desarrollo (AECID, Spain) through Accion Integrada MAEC-AECID MEDITERRANEOSecurity Engineering Research Center - Ministry of Knowledge Economy (MKE, Korea)pu

A DHCP-based IP address autoconfiguration for MANETs

Mobile Ad hoc Networks (MANETs) are expected to become more and more important in the upcoming years, playing a significant role in 4G networks. In order to enable the deployment of IP services in such networks, IP address autoconfiguration mechanisms are required. Although the ad hoc topic has been a very intense research area, with a plethora of published papers about routing, there is a lack of proposals of address autoconfiguration with enough support from the technical community. This paper presents a mechanism suited for MANETs connected to the Internet, reusing existing and widely deployed address autoconfiguration protocols, such as DHCPv6 and Router Advertisements

Coherent, automatic address resolution for vehicular ad hoc networks

Published in: Int. J. of Ad Hoc and Ubiquitous Computing, 2017 Vol.25, No.3, pp.163 - 179. DOI: 10.1504/IJAHUC.2017.10001935The interest in vehicular communications has increased notably. In this paper, the use of the address resolution (AR) procedures is studied for vehicular ad hoc networks (VANETs). We analyse the poor performance of AR transactions in such networks and we present a new proposal called coherent, automatic address resolution (CAAR). Our approach inhibits the use of AR transactions and instead increases the usefulness of routing signalling to automatically match the IP and MAC addresses. Through extensive simulations in realistic VANET scenarios using the Estinet simulator, we compare our proposal CAAR to classical AR and to another of our proposals that enhances AR for mobile wireless networks, called AR+. In addition, we present a performance evaluation of the behaviour of CAAR, AR and AR+ with unicast traffic of a reporting service for VANETs. Results show that CAAR outperforms the other two solutions in terms of packet losses and furthermore, it does not introduce additional overhead.Postprint (published version

Service and device discovery of nodes in a wireless sensor network

Emerging wireless communication standards and more capable sensors and actuators have pushed further development of wireless sensor networks. Deploying a large number of sensor\ud nodes requires a high-level framework enabling the devices to present themselves and the resources they hold. The device and the resources can be described as services, and in this paper, we review a number of well-known service discovery protocols. Bonjour stands out with its auto-configuration, distributed architecture, and sharing of resources. We also present a lightweight implementation in order to demonstrate that an emerging standards-based device and service discovery protocol can actually be deployed on small wireless sensor nodes
