The shift towards 6G networks is expected to be accompanied by an increased capability support group-oriented services, such as extended reality and holographic communications, in many different contexts, from high-precision manufacturing healthcare remote control. This range of applications will rely heavily on multicast mixed multicast-broadcast delivery modes. article focuses the technologic...

As WDM technology matures, IP over WDM multicast becomes a new challenging topic. Supporting multicast at the WDM layer provides additional advantages, but also raises many new issues that do not exist in IP multicast. For example, the limitation on the light splitting capability of switches is one major difficulty in WDM multicast, and in addition, the limitations on both the wavelength conver...

Recently, audio and video delivery services are widely spread in the Internet. In order to deliver these data to multiple receivers at the same time, the multicast technologies are indispensable. In such a situation, the performance analysis of multicast traffic will be important in order to design and operate the Internet. Multicast traffic is controlled by its own routing protocol and the mul...

This study discusses the problem of key distribution protocol in IoT systems especially smart grids for two modes communication: Unicast and multicast. In present paper, we suggested protocols both unicast multicast communication. The proposed schemes are based on symmetric encryption with cryptographic primitives: Hashes nonces. addition, is a logical hierarchy to reduce communication computat...

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 ...

We propose and analyze a multicast algorithm named Dynamic Agent-based Hierarchical Multicast (DAHM) for wireless mesh networks that supports user mobility and dynamic group membership. The objective of DAHM is to minimize the overall network cost incurred. DAHM dynamically selects multicast routers serving as multicast agents for integrated mobility and multicast service management, effectivel...

Recently several multicast mechanisms [3], known as small group multicast, were proposed that scale better with the number of multicast sessions than traditional multicast does. In this paper, we propose a new approach, Simple Explicit Multicast (SEM), which uses an efficient method to construct multicast trees and deliver multicast packets. SEM is original because it adopts the source-specific...
