Multicast routing is a key technology for modern communication networks. It sends a single copy of a message from a source to multiple receivers over a communication link that is shared by the paths to the receivers. This is especially appropriate in wireless environments where bandwidth is scarce and many users are sharing the same wireless channels. In particular, for WMNs, multicast can repr...

In this paper, we propose a new hardware tree-based routing algorithm (HTA) for multicast communication under virtual cut-through switching in k-ary n-cubes that out-performs existing software and hardware path-based multicast routing schemes. Simulation results are compared against several commonly used multicast routing algorithms and show that HTA performs extremely well under many different...

Multicast communication is one of particular important services in peer-to-peer networking context. The problem of finding a minimum cost multicast routing is NP-completeness. We present a novel solution to improve the MPH algorithm. The cost of multicast tree generated by the proposed algorithm with the same time as MPH is not larger than that of MPH in the worst case.

In this paper we evaluate a spectrum of various approaches to group communication for MIPv6 nodes: Network Layer Multicast (IP multicast), Application Layer Multicast(ALM) and a hybrid approach. Based on a previous comparison of the two extremes, we focus on the hybrid solution and we propose a number of optimizations. Our results show that although IP Multicast is still the best option in term...

In the paper, we consider a preference heterogeneity problem in large-scale multicast applications. Abundant content, data type and diverse members’ interests naturally lead to preference heterogeneity within a multicast session requiring frequent communication within subgroups of members sharing common interests/requirements. In this paper, we take an overlay approach which builds topology-sen...

Multicast service, which is one of the multi-point communication methods, should be applied to adjust it to evolving mobile network environment. In this paper, we propose a fast multicast management scheme for mobile terminals in HMIPv6-based mobile networks. In HMIPv6-based mobile network environment, multicast management scheme provides multicast service during mobile handover depending on th...

In this paper we solve the problem of secure communication in multicast graphs, which has been open for over a decade. At Eurocrypt ’98, Franklin and Wright initiated the study of secure communication against a Byzantine adversary on multicast channels in a neighbor network setting. Their model requires node-disjoint and neighbor-disjoint paths between a sender and a receiver. This requirement ...

This paper presents a technique to provide seamless communication in mobile wireless networks. The goal of seamless communication is to make the motion of a mobile host transparent to the applications executing on it. Active handoos (handoos during an active connection) cause pauses in communication between the mobile host and the xed network, resulting in applications seeing a substantial perf...

As the variety of applications, especially distributed multimedia applications, explodes, their requirements on communication-relevant tasks increase. Besides a communication architecture for dealing with traditional communication protocol processing, multicast features and security requirements have to be considered in an integrated manner. Therefore, a multicast-capable and security-aware com...

New high speed networks and the requirements of users for the support of interpersonal communication in a computerised heterogeneous environment demand for new communication services. These services have to provide support for multimedia group communication. In this paper we introduce a multicast transport service for multimedia group applications called M-Connection Service. It is a protocol i...
