Tree-Based Distributed Multicast Algorithms for Directional Communications and Lifetime Optimization in Wireless Ad Hoc Networks

EURASIP Journal on Wireless Communications and Networking, 2007
We consider the problem of maximizing the network lifetime in WANETs (wireless ad hoc networks) with limited energy resources using omnidirectional or directional antennas.

Efficient Key Agreements in Dynamic Multicast Height Balanced Tree for Secure Multicast Communications in Ad Hoc Networks

EURASIP Journal on Wireless Communications and Networking, 2011
Alterations and unpredictability of the network topology in mobile ad hoc networks (MANETs) are less capable of ensuring the security of multicast data transmissions than in conventional networks.

Novel wire-speed multicast self-routing switch fabric based on Boolean concentrator

Tongxin xuebao, 2014
The traditional multicast switch fabrics (MSF) are mainly developed from the unicast switch fabrics (USF). Owing to the bottleneck of the current USF, almost all the existing MSF are not able to achieve high efficiency orexcel-lentlarge-scale scalability.
