Multicast communication is an efficient method of data transmission and distribution among a group, especially when network resources are inadequate and needs to be shared. Fair share of network resources, such as, bandwidth, is desirable in such cases. Although there has been an intensive research effort to design protocols and construct multicast routing graphs for a single multicast group, construction...
In this paper, we propose a bandwidth-efficient multicast mechanism for heterogeneous wireless networks. We reduce the bandwidth cost of an Internet protocol (IP) multicast tree by adaptively selecting the cell and the wireless technology for each mobile host to join the multicast group. Our mechanism enables more mobile hosts to cluster together and leads to the use of fewer cells to save the scarce...
Telecommunication networks are subject to failures which may be complex. Fast-reroute implementations have been proposed for Multiprotocol Label Switching (MPLS) networks to make it possible to reroute traffic locally in case of failure. Hence, to each link is associated a bypass tunnel usable if the link fails. These protection tunnels can be pre-calculated in a centralized manner, that ensures faster...
