Providing multicast service to mobile hosts in wireless mobile networking environments is difficult due to frequent changes of mobile host location and group membership. If a conventional multicast routing protocol is used in wireless mobile networks, several problems may be experienced since existing multicast routing protocols assume static hosts when they construct the multicast delivery tre...

This paper shows that, for single-hop WDM networks, a multicast scheduling algorithm which always tries to partition a multicast transmission into multiple unicast or multicast transmissions may not always produce lower mean packet delay than a multicast scheduling algorithm which does not partition multicast transmissions. The performance of a multicast scheduling algorithm may depend on the t...

Many applications can benefit from ubiquitous availability of multicast delivery. Unfortunately IP multicast coverage on the Internet is spotty at best, limited to individual campuses and a handful of service providers. In response to the slow deployment of IP multicast, a number of end-host multicast mechanisms have been developed. End-host multicast lowers the deployment barrier of multicast ...

Abstract Linear broadcasting services, with a scheduled programming, constitute paramount telecommunication service for today’s society. Although the existing technology is mature, current linear broadcast systems have serious limitations when providing to moving users or placed in areas complex orography and poor signal quality. To overcome these limitations, 3GPP 5G standard has included work...

Multicast state scalability is among the critical issues which delay the deployment of IP multicast. In our previous work, we proposed a scheme, called aggregated multicast to reduce multicast state. The key idea is that multiple groups are forced to share a single delivery tree. We presented some initial results to show that multicast state can be reduced, sometimes at the expense of bandwidth...

While the advantages of multicast delivery over multiple unicast deliveries is undeniable, the deployment of the IP multicast protocol has been limited to “islands” of network domains under single administrative control. Deployment of inter-domain multicast delivery has been slow due to both technical and administrative reasons. In this paper we propose a Host Multicast Tree Protocol (HMTP) tha...

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...
