Many applications are inherently multicast in nature. Such applications can benefit tremendously from reliable multicast support at the MAC layer since addressing reliability at the MAC level is much less expensive than handling errors at the upper layers. However, the IEEE 802.11 MAC layer does not support reliable multicast. This void in the MAC layer is a limiting factor in the efficacy of m...

Providing multicast service to mobile hosts in wireless mobile networking environments is difficult due to frequent changes of mobile host location and group membership. If a conventional multicast routing protocol is used in wireless mobile networks, several problems may be experienced since existing multicast routing protocols assume static hosts when they construct the multicast delivery tre...

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...

Group communication protocols are used in fault-tolerant systems to maintain strong replica consistency. The FaultTolerant Multicast Protocol (FTMP) described here is a group communication protocol specifically designed for the Common Object Request Broker Architecture (CORBA). FTMP operates over IP Multicast, and consists of the Reliable Multicast Protocol (RMP) that provides reliable source-o...

In this paper we give an overview of open-source and commercial multicast routing solutions. XORP (eXtensible Open Router Platform) is the only system which includes support for the multicast management and multicast routing protocol. We provided support for the multicast routing and multicast routing protocol (PIM sparse mode) in the core of the Linux operating system and developed an advanced...

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...

We propose a protocol that controls the members of a multicast group that send periodically status reports to all members. The protocol, called Multicast Access Protocol (MAP), limits the number of concurrent multicast reports as the group size becomes large. MAP is a decentralised protocol that provides an access control mechanism to an IP multicast group. The protocol supports members joining...

We propose the efficient reliable multicast MAC protocol based on the connectivity information among the recipients. Enhancing the BMMM (Batch Mode Multicast MAC) protocol, the reliable multicast MAC protocol significantly reduces the RAK (Request for ACK) frame transmissions in a reasonable computational time and enhances the MAC performance. By the analytical performance analysis, the through...
