CSCW applications require availability, portability, familiarity, scalability, bandwidth and performance. This paper describes the use of Web-multicasting to address these issues. Web-multicasting is a concept that use a standard Web-browser to communicate between multiusers. The web-browser will use multicasting methods, so that no Web server is necessary needed. A prototype Web-multicast Chat...

Simultaneous transmission of data from one sender to multiple receivers is called multicasting. Several widely used applications require multicasting at least at the logical level. Examples include audio video teleconferencing, real time video streaming and the maintenance of distributed databases. In many cases it is advantageous to implement multicasting at the level of the routing algorithm ...

Multicasting multimedia streams in IEEE 802.11 wireless LANs has two issues: reliability and rate adaptation. We address these issues by proposing two mechanisms that augment the current multicasting standards in a backward-compatible fashion. Semi-reliable multicasting (SRM) selects a leader who sends feedback information to lessen the reliability problem of multicast frames. Probing-based aut...

As multimediaand group-oriented computing becomes increasingly popular for the users of wireless mobile networks, the importance of features like quality of service (QoS) and multicasting support grows. Ad hoc networks can provide users with the mobility they demand, if efficient QoS multicasting strategies are developed. The ad hoc QoS multicasting (AQM) protocol achieves multicasting efficien...

One of the dominant questions facing the Internet today is, how can the network meet the needs of the users and their applications (QoS) while trying to keep such implementations scalable to the billions of users present on the Internet? Two of the emerging technologies for answering this question are Differentiated Services (DiffServ) and multicasting. Although both are complementary technolog...

Multicasting can be done in two different ways: source based tree approach and shared tree approach. Protocols such as Core Based Tree (CBT), Protocol Independent Multicasting Sparse Mode (PIM-SM) use shared tree approach. Shared tree approach is preferred over sourcebased tree approach because in the later construction of minimum cost tree per source is needed unlike a single shared tree in th...

This memo specifies the extensions required of a host implementation of the Internet Protocol (IP) to support internetwork multicasting. This specification supersedes that given in RFC-966, and constitutes a proposed protocol standard for IP multicasting in the ARPA-Internet. The reader is directed to RFC-966 for a discussion of the motivation and rationale behind the multicasting extension spe...

This paper considers multicasting on wavelength-routing mesh optical networks. Although multicasting has been studied extensively in different network environments, multicasting in this environment is different, and more involved. The paper discusses the challenges of multicast support in optical wavelength routing networks, and reports on the advances made so far in this venue. The paper intro...

We report multicasting data from a single orbital angular momentum (OAM) spatial channel onto multiple OAM channels of equally spaced OAM charge numbers. The designed sliced phase patterns for multicasting are loaded on the spatial light modulator. By optimizing the design of the phase pattern, the power of multicasted OAM channels can be equalized. We experimentally demonstrate multicasting fi...

In duty-cycled wireless sensor networks, the nodes switch between active and dormant states, and each node determine its active/dormant schedule independently. This complicates the Minimum Energy Multicasting (MEM) problem in wireless sensor networks both for one-to-many multicasting and for all-to-all multicasting. In the case of one-to-many multicasting, we present a formalization of the Mini...
