The phenomenal growths of group communications and QoS-aware applications over the Internet have respectively accelerated the development of two key technologies, namely, multicasting and Differentiated Services (DiffServ). Although both are complementary technologies, the integration of the two technologies is a non-trivial task due to architectural conflicts between multicasting and DiffServ....

Mobile Ad-hoc networks are characterized as networks without any physical connections. In these networks there is no fixed topology due to the mobility of nodes, interference, multi-path propagation and path loss. One particularly challenging environment for multicast is a mobile ad-hoc network (MANET), where the network topology can change randomly and rapidly, at unpredictable times. As a res...

After a decade of research and development, IP multicast has still not been deployed widely in the global Internet due to many open technical issues: lack of admission control, poorly scaled with large number of groups, and requiring substantial infrastructure modifications. To provide the benefits of IP multicast without requiring direct router support or the presence of a physical broadcast m...

Increasing multimedia applications such as teleconferencing and video-on-demand require the Internet to effectively provide high-performance multicast support. One of the promising solutions for multicasting is called end-system multicasting, in which the multicasting is conducted either at the end systems or at a dedicated Multicast Service Node (MSN). A MSN is responsible for a number of end ...

Multicasting is a desired function in both wired and wireless networks. Currently, multicasting-based applications have pervasive presence and influence in our Internet. Wireless ATM aims to support different traffic types over a high speed wireless network. In particular, traditional approaches towards multicasting in wired networks cannot be directly applied to mobile ATM networks. This inclu...

In current Mobile Adhoc Network (MANET) scenario of social network, Delay Tolerant Networks (DTNs) are needed to handle frequent network partitions and large end-to-end delays for efficient multicasting. Existing scheme presented adaptive multicast routing to handle multicast delivery schemes for DTNs. However performance and reliability obtained on sparsely connected nodes in the MANET social ...

Explicit routing in MPLS is utilized in traffic engineering to maximize the operational network performance and to provide Quality of Service (QoS). However, difficulties arise while integrating native IP multicasting with MPLS traffic engineering, such as point-to-multipoint or multipoint-to-multipoint LSPs layout design and traffic aggregation. In this paper, we have proposed an edge router m...

Recently, soft video multicasting has gained a lot of attention, especially in broadcast and mobile scenarios where the bit rate supported by channel may differ across receivers, vary quickly over time. Unlike conventional designs that force source to use single according receiver with worst quality, delivery schemes transmit such quality at each is commensurate its specific instantaneous quali...
