Usability of legacy p2p multicast in multihop ad hoc networks: an experimental study

There has recently been an increasing interest in convergence of p2p and ad hoc network research. Actually, p2p systems and multihop ad hoc networks share similar features, such as self-organisation, decentralisation, self-healing, and so forth. It is thus interesting to understand if p2p systems designed for the wired Internet are suitable also for ad hoc networks and, if they are not, in which direction they should be improved. In this paper, we report our experience in running p2p applications in real multihop ad hoc network testbeds. Specifically, we used group-communication applications that require p2p systems made up of an overlay network and a p2p multicast protocol. In this paper, we present experimental results specifically related to the performance of a well-known p2p shared-tree multicast protocol (Scribe). Our results show that such a solution is far from being efficient on ad hoc networks. We emphasize that the structured multicast approach is one of the main causes of inefficiency, and suggest that stateless solutions could be preferable

A Review of the Energy Efficient and Secure Multicast Routing Protocols for Mobile Ad hoc Networks

This paper presents a thorough survey of recent work addressing energy efficient multicast routing protocols and secure multicast routing protocols in Mobile Ad hoc Networks (MANETs). There are so many issues and solutions which witness the need of energy management and security in ad hoc wireless networks. The objective of a multicast routing protocol for MANETs is to support the propagation of data from a sender to all the receivers of a multicast group while trying to use the available bandwidth efficiently in the presence of frequent topology changes. Multicasting can improve the efficiency of the wireless link when sending multiple copies of messages by exploiting the inherent broadcast property of wireless transmission. Secure multicast routing plays a significant role in MANETs. However, offering energy efficient and secure multicast routing is a difficult and challenging task. In recent years, various multicast routing protocols have been proposed for MANETs. These protocols have distinguishing features and use different mechanismsComment: 15 page

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

Realistic, Extensible DNS and mDNS Models for INET/OMNeT++

The domain name system (DNS) is one of the core services in today's network structures. In local and ad-hoc networks DNS is often enhanced or replaced by mDNS. As of yet, no simulation models for DNS and mDNS have been developed for INET/OMNeT++. We introduce DNS and mDNS simulation models for OMNeT++, which allow researchers to easily prototype and evaluate extensions for these protocols. In addition, we present models for our own experimental extensions, namely Stateless DNS and Privacy-Enhanced mDNS, that are based on the aforementioned models. Using our models we were able to further improve the efficiency of our protocol extensions.Comment: Published in: A. F\"orster, C. Minkenberg, G. R. Herrera, M.

Effective Multicast Routing Protocol for Ad Hoc Networks

Most of the multicast routing protocols depend on creation of multicast tree for the transmission of packet from source to destination, which leads to maintain states of the neighboring node and it incures more cost. Maintaining the states of nodes also increases communication and processing overhead as well as requires more amount of memory. Almost all protocols maintain the path list in their routing table which also increases overhead while routing the packets. In this paper we developed a stateless receiver-based multicast routing protocol that includes a list of the multicast destination members addresses (sinks), added in packet headers, to enable receivers to decide the best way to forward the multicast traffic

Multicast Conventions to Improve Obstacle Detection and Collusion Avoidance in MANET

As of late, it got to be obvious that gathering focused administrations are one of the essential application classes focused by MANETs. In spite of the fact that these conventions perform well under particular versatility situations, movement loads, and system conditions, no single convention has been appeared to be ideal in all situations. The objective of this paper is to describe the execution of multicast conventions over an extensive variety of MANET situations. To this end, we assess the execution of lattice and tree-based multicast steering plans in respect to flooding and prescribe conventions most reasonable for particular MANET situations. In view of the investigation and reproduction results, we likewise propose two varieties of flooding, Perused flooding and hyper flooding, as a way to diminish overhead and expansion unwavering quality, separately. Another commitment of the paper is a recreation based relative investigation of the proposed flooding varieties against plain flooding, work, and tree-based MANET directing. In this paper we researched about various sending technique for GPSR in remote system furthermore discover the issues and their answers. The principle point of our study was to distinguish which directing strategy has better execution in very versatile environment of VANET. In MANET, this depletion of vitality will be more because of its infrastructure less nature and versatility. Because of this, the topology get shifted. This may definitely influence the execution of steering convention furthermore influence the system lifetime. To address this issue another calculation has been created which uses the system parameters identifying with element nature of hubs viz. vitality channel rate, relative versatility estimation to foresee the hub lifetime and connection lifetime. At that point execute this calculation in the DYMO convention environment. This will expand the system lifetime and adaptability. Further enhance the execution, we have actualized another calculation by incorporating course lifetime expectation calculation alongside the molecule swarm enhancement (PSO) calculation
