Due to the pruning and joining of members, multicast groups are dynamic. Both the topology and the total number of links change during multicast sessions, and the multicast performance, measured in terms of the bandwidth consumption, will change accordingly. In this paper, we investigate the dynamic performance of multicast communication with homogeneous packet loss probability; indeed, we eval...

In today’s Internet, the need for multimedia communication leads to rapid progress in multicast technology. Using multicast can efficiently deliver packets to a group of receivers. Compared with unicast, multicast can significantly reduce the bandwidth demand in networks. In the meantime, with the wide use of mobile devices and the introduction of Mobile IP, people can contact with the Internet...

The IP multicast model allows scalable and efficient multi-party communication, particularly for groups of large size. However, deployment of IP multicast requires substantial infrastructure modifications and is hampered by a host of unresolved open problems. To circumvent this situation, we have designed and implemented ALMI, an application level group communication middleware, which allows ac...

This paper identifies the basic functions required from a communication subsystem in order to support a distributed, reliable, reconfigurable, and replicated database environment. These functions include: reliable multicast, remote procedure calls (RPC) , inexpensive datagram services, and efficient local interprocess communication (IPC). Data obtained via a series of experiments that measure t...

IP Multicast has been developed in the past few years to support multi-point communication in Internet. However, it is still hard for protocol designers to tackle the intrinsic heterogeneity of networks and end-systems. Moreover, in practical, current Internet is not fully multicast-enabled. In this paper, we present a practical semantic reliable multicast (PSRM) architecture for current Intern...

This paper proposes an access control protocol method for multicast transmission to reduce packet loss caused by collisions and/or interferences in WLAN (wireless local area network) systems. Multicast transmission may achieve effective bandwidth use because packets are delivered to more than one mobile station simultaneously in single transmissions. However, because multicast transmission does...

Multimedia applications often involve one-to-many, or manyto-many, communication. These applications can be supported efficiently with network layer multicast. While multicast is a promising technology, monitoring multicast routing infrastructure and the performance of applications that use it presents challenges not found with unicast. In this paper we describe a monitoring architecture, and a...

Multicast routing is one of the most important services in Multi Radio Multi Channel (MRMC) Wireless Mesh Networks (WMN). Multicast routing performance in WMNs could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. In this paper we want to address the multicast routing problem for a given channel assignment in WMNs. The channels...

Today’s cellular communication networks offer seamless mobility support but are based on a homogeneous networking technology and a complex voice-oriented networking infrastructure. The Internet technology is expected to cause a paradigm shift in cellular communication networks. Mobile IP is the classical solution to support host mobility, but faces a number of disadvantages, including triangula...

An ad-hoc network is the cooperative engagement of a collection of (typically wireless) mobile nodes without the required intervention of any centralized access point or existing infrastructure. To provide optimal communication ability, a routing protocol for such a dynamic self-starting network must be capable of unicast, broadcast , and multicast. In this paper we extend Ad-hoc On-Demand Dist...
