Multicast Optimized Link State Routing

This document describes the Multicast extension for the Optimized Link State Routing protocol (MOLSR). MOLSR is in charge of building a multicast structure in order to route multicast traffic in an ad-hoc network. MOLSR is designed for mobile multicast routers, and works in a heterogenous network composed of simple unicast OLSR routers, MOLSR routers and hosts. In the last part of this document we introduce also a Wireless Internet Group Management Protocol (WIGMP). It offers the possibility for OLSR nodes (without multicast capabilities) to join multicast groups and receive multicast data

Reliable Multicast in Heterogeneous Mobile Ad-hoc Networks

In disaster scenarios, communication infrastructure could be damaged orcompletely failed. Mobile Ad-hoc Networks (MANETs) can be used to substitutefailed communication devices and thus to enable communication. As group communicationis an important part in disaster scenarios, multicast will be used to addressseveral nodes. In this paper, we propose our new reliable multicast protocol RMDA(Reliable Multicast over Delay Tolerant Mobile Ad hoc Networks). We introducean efficient group management approach and a new method for reliable multicastdelivery over Delay Tolerant Networks. We show, that our protocol is adaptive todifferent kinds of MANETs, e.g. with or without clusterheads, respectively. Forthose without, we use our name resolution over adaptive routing approach

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
