We present the Preemptive Bandwidth Allocation Multicast Protocol; a distributed multicast QoS-aware signaling protocol that adapts the users’ bandwidth requirements to the limited resources available in the network by preempting bandwidth of less prioritized streams from existing multicast groups. We assume that each multicast group will have different multicast streams with predefined quality...

Multicasting is effective when its group members are sparse and the speed is low. On the other hand, broadcasting is effective when the group members dense and the speed are high. Since mobile ad hoc networks are highly dynamic in nature, either of the above two strategies can be adopted at different scenarios. In this paper, we propose an ant agent based adaptive, multicast protocol that explo...

In this paper we present an extension to the OLSR unicast routing protocol to support multicast routing in mobile ad hoc networks. The proposed protocol is based on Multicast Overlay Spanning Trees (MOST). The main benefits of this approach are twofold. Firstly, it implies that only nodes interested in taking part in the multicast communication need to participate in the protocol operation, whi...

A multicast protocol is ordered (or totally ordered) if it ensures that messages multicast to a group of nodes are delivered in the same order at each destination node, even when those messages are generated concurrently from several sources. Ordered multicast is a natural foundation for push-based cache coherence and certain kinds of middleware. This paper shows how to reduce the complex probl...

Source Specific Multicast (SSM) is a viable solution for current multicast applications, since the driving applications to date are one to many, including Internet TV, distance learning, file distribution and streaming media, etc. It brings many benefits in billing, address allocation, and security. However, SSM still confronts the serious state scalability problem when there are a large number...

Management has become a key concern for the success of multicast deployment in the Internet. One of the most important management tasks for multicast is to verify the availability of the service to its users. This task is referred to as discovering or testing reachability. In this paper, we present a new mechanism, SSM-Ping, for discovering multicast reachability between (remote) end systems in...

In general IP multicast supports location-independent addressing and routing for a group of hosts. This ability is similar to the requirement for mobility support in IP-based networks though in a different context. MOMBASA stands for “MObility support – a Multicast BASed Approach”. It is intended to utilise multicast in order to support network level mobility. The basic mechanism of a multicast...

Nodes mobility brings flinty challenges to multicast in Mobile ad hoc Networks (MANETs). To track nodes mobility, flooding messages are widely used for data delivery structure construction and maintenance in many multicast protocols. These periodic flooding messages significantly consume network resources, such as energy and bandwidth, and result in network collisions. To release data delivery ...

The Internet Group Management Protocol Version 3 (IGMPv3) and the Multicast Listener Discovery Protocol Version 2 (MLDv2) are protocols that allow a host to inform its neighboring routers of its desire to receive IPv4 and IPv6 multicast transmissions, respectively. Source-specific multicast (SSM) is a form of multicast in which a receiver is required to specify both the network-layer address of...

In the age of multimedia and high-speed networks, multicast is one of the mechanisms by which the power of the Internet can be further harnessed in an efficient manner. When more than one receiver is interested in receiving a transmission from a single or a set of senders, multicast is the most efficient and viable mechanism. In the protocol stack of the network, multicast is best implemented i...
