The Core-Assisted Mesh Protocol (CAMP) is introduced for multicast routing in ad-hoc networks. CAMP generalizes the notion of core-based trees introduced for internet multicasting into multicast meshes that have much richer connectivity than trees. A shared multicast mesh is defined for each multicast group; the main goal of using such meshes is to maintain the connectivity of multicast groups ...

IP multicast confronts a severe scalability problem when there are large numbers of multicast groups in the network due to state explosion and control explosion. In backbone networks, this state scalability problem is exacerbated, since there are potentially enormous multicast groups crossing backbone domains. To improve the state scalability of multicast in backbone domains, in this paper, we ...

In reliable multicast communications, transmission rate of a sender should be restricted to the node capability of the lowest node in order to support reliable transmission of packets to all receivers in a multicast group. Even a node of high capability should receive packets at lower rate when there are lower capability nodes in a corresponding multicast group. In reliable multicast communicat...

Multicast/broadcast delivery is a critical challenge of future 6G mobile networks where massive Internet Things (IoT) deployment and extended reality multimedia such as teleportation are target application scenarios. Non-terrestrial (NTNs) considered essential for the success 6G, which aims to provide true “global” services by extending access worldwide, thus overcoming coverage limit current t...

Large parts of the Internet are still incapable of native multicast, and ubiquitous deployment of multicast will take a long time. There are two approaches to provide wide-area multicast service in today’s Internet. One is tunneling approach and the other is application-level multicast approach. In this paper, we focus on application-level multicast approach and propose a new scheme which impro...

Quantum multicast is a significant transmission mode in multiparty communication scenario. Multisource collaboration can further enhance the efficient multicast. However, it remains challenge to realize quantum with cooperative way complex topology network. In this article, we propose scheme of hybrid It provides information aggregation and simultaneous multipoint services. First, collaborative...
