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...

This paper describes mobile backhaul optical access network designs for future cellular systems, in particular, for those systems that exploit coordinated multipoints (CoMP) transmission/reception techniques. Wavelength-division-multiplexing passive optical networks (WDM-PON) are primarily considered and two proposals to enhance mobile backhaul capability of WDM-PONs for CoMP are presented. One...

Supporting WDM multicasting in an IP over WDM network poses interesting problems because some WDM switches may be incapable of switching an incoming signal to more than one output interface. An approach to WDM multicasting based on wavelength-routing, which constructs a multicast forest for each multicast session so that multicast-incapable WDM switches do not need to multicast, was proposed an...

Hybrid CDN-P2P networks blend CDN and P2P technology to benefit from the complementary advantages of these technologies. In these networks, a critical challenge is to construct and maintain multicasting trees to distribute the content from distribution servers to the edge servers, clients and peers. In this work considering tight relation between internal and P2P layers of these networks, a sin...

In this paper 1 we are concerned with disseminating high-volume data streams to many simultaneous applications over a low-bandwidth wireless mesh network. For bandwidth efficiency, we propose a group-aware stream filtering approach, used in conjunction with multicasting, that exploits two overlooked, yet important, properties of these applications: 1) many applications can tolerate some degree ...

Multicasting is an important communication paradigm for enabling the dissemination of information selectively. This paper considers the problem of optimal secure multicasting in a communication network captured through a graph ( optimal is in an interesting sense) and provides a doubly optimal solution using results from source coding. It is realized that the solution leads to optimal design ( ...

TCP/IP is currently the standard network protocol for wired Internet. To make all Internet services available to all mobile users, a Mobile IP is proposed. Another important development for TCP/IP is the evolution to the next generation Internet, the protocol for which is called IPv6. Whether using IPv4 or IPv6, situations arise in some Internet applications where a piece of data needs to be se...

90 ulticasting is the ability of a communication network to accept a single message from an application and to deliver copies of the message to multiple recipients at different locations. One of the challenges is to minimize the amount of network resources employed by multicasting. To illustrate this point, let us assume that a video server wants to transmit a movie to 1000 recipients (Fig. 1a)...

Multicasting is an efficient means of one to many communication and is typically implemented by creating a multicasting tree. Because of the severe battery power and transmission bandwidth limitations in ad hoc networks, multicast routing can significantly improve the performance of this type of network. However, due to the frequent and hard-to-predict topological changes of ad hoc networks, ma...

In this thesis, we will present solutions for end users on how to profit from efficient data transmission and dissemination using multicasting with Quality of Service (QoS) support. Multicasting is one of the most efficient mechanisms to distribute data from one sender to multiple receivers concurrently. Since IP Multicasting is not widely deployed in the Internet today, Overlay Multicast has b...
