On the Construction of Virtual Multicast Backbone for Wireless Ad Hoc Networks

Overview With the proliferation of portable computing devices and ascending popularity of group-oriented computing, wireless ad hoc network multicasting remains a challenging research subject. While Virtual Multicast Backbone (VMB) structure are commonly used in current multicast protocols, this paper focuses on the construction of the optimal VMB with the fewest forwarding nodes to decrease overhead and cost, due to the scarce resource in ad hoc networks. Instead of conventional Steiner tree model, the optimal shared VMB in ad hoc networks is modeled as Minimum Steiner Dominating Set (MSCDS) in Unit-Disk Graphs (UDG), which is NP-hard.

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
