We propose a reliable multicast MAC protocol based on the multicarrier direct-sequence code-division multiple access (MC DS-CDMA) scheme to enhance spatial reuse efficiency in wireless local area networks (WLANs). Conventional multicast MAC protocols using RTS-CTS handshake exchange CTS and ACK packets consecutively for reliable transmission. Although this protocol guarantees transmission relia...

Multicast routing is a key technology for modern communication networks. It sends a single copy of a message from a source to multiple receivers over a communication link that is shared by the paths to the receivers. This is especially appropriate in wireless environments where bandwidth is scarce and many users are sharing the same wireless channels. In particular, for WMNs, multicast can repr...

Despite the fact that global multicast is still not possible in today’s Internet, many local networks are already multicast-capable (the so-called multicast “islands”). However, most application-layer multicast (ALM) protocols for streaming have not taken advantage of the underlying IP multicast capability. As IP multicast is more efficient, it would be beneficial if ALM can take advantage of s...

This paper proposes a new multicast protocol for Mobile Ad Hoc networks, called the Multicast routing protocol based on Zone Routing (MZR). MZR is a source-initiated ondemand protocol, in which a multicast delivery tree is created using a concept called the zone routing mechanism. It is a source tree based protocol and does not depend on any underlying unicast protocol. The protocol’s reaction ...

In this paper, we present a protocol for providing reliable multicast message delivery in mobile networks. Our protocol eeciently tracks message delivery and allows for reliable message delivery in an environment where the mobile multicast group experiences frequent adds and drops. Furthermore, our protocol allows group changes and message tracking to be handled locally, which translates to sho...
