Multicast service with Quality of Service (QoS) guarantees is critical to commercial and real-time applications , such as telemedicine, video-conferencing, and virtual reality. The Internet is currently in the process of developing QoS architectures (e.g., Int-serv, Dii-serv) to support such applications. However, most multicast protocols, such as PIM and CBT, do not employ QoS-sensitive routin...

Existing multicast traffic engineering (TE) solutions tend to use explicit routing through MPLS tunnels. In this paper we shift away from this overlay approach and address the bandwidth constrained IP multicast TE directly based on link state IGP routing protocols. The objective is that, through plain PIM-SM shortest path routing with optimized Multi-topology IS-IS (MISIS) link weights, the res...

The Adaptive Core Multicast Routing Protocol (ACMRP) is proposed for multicast routing in ad hoc networks. ACMRP is on demand core-based multicast routing protocol and uses a multicast mesh. In ACMRP, a core is not well-known and it adapts to the current network topology and group membership. The enhanced adaptivity minimizes the core dependency and, accordingly, improves performance and robust...

Typically, multicast data distribution uses rendezvous points (PIM, CBT), multicast distribution tree building protocols, and multicast forwarding. Whereas the first two approaches have been extensively studied, scaling multicast forwarding state without increasing forwarding complexity has not been addressed in detail. Having a scalable strategy for aggregation of multicast forwarding state is...

In mobile ad-hoc network, some multi -channel MAC protocols utilize multiple channels to reduce the collision of wireless transmission and thus get high throughput. These multi channel MAC protocols aim at improving the performance of unicast communication, and multicast data are generally transmitted through broadcast. So multicast can’t benefit from the multi -channel technique. This paper pr...

EEcient multicast communication provides one of the best avenues for scaling bandwidth intensive applications. Current multicast routing mechanisms perform well for multicast groups which reach a long-term, steady-state distribution of membership. However, when the membership migrates throughout the network, current routing techniques may perform poorly. One type of multicast routing technique ...

QOSPF [6-8] is a well-known link state based unicast QoS routing protocol. It is a precomputation-based approach with the strength of low routing latency but suffers from high control and storage overheads. Its overhead will be exacerbated not only for large-scale network but also for the extension to support multicast routing. Thus, few researches strive to directly extend the work of QOSPF to...

This paper presents a performance analysis of topological and geographical multicast routing algorithms for mobile wireless ad hoc networks. Flooding and On-Demand Multicast Routing Protocol (ODMRP) are simulated and compared with two novels protocols proposed: Topological Multicast Routing Protocol (ToMuRo) and Geographical Multicast Routing Protocol (GeMuRo) in pedestrian and vehicular scenar...

The IP Multicast architecture was not widely deployed because multicast address allocation is difficult and there is no scalable solution to inter-domain multicast routing. Hence, there is an interest in developing protocols that allow the progressive deployment of the multicast service by supporting unicast clouds. This paper proposes HBH (Hop-By-Hop multicast routing protocol). HBH adopts the...

In this paper, we investigate the well-known state dependent multicast routing algorithm called Least Load Multicast Routing (LLMR), for single rate loss networks. The algorithm is based on the Least Load Routing (LLR) concept and the approach is to select the least load links for establishing connections. We propose a modiied version, called Ag-gregated Least Load Multicast Routing (ALLMR), wh...
