Distributed Approximation Algorithms for Longest-Lived Multicast in WANETs with Directional Antennas
IEEE Transactions on Wireless Communications
We consider the lifetime optimization problem for multicasting in wireless ad hoc networks, in which each node is equipped with a directional antenna and has limited energy supplies. Several distributed algorithms proposed recently are especially beneficial to a resource-constrained wireless ad hoc network. In this paper, we propose a new distributed algorithm and investigate its theoretical performance compared to existing distributed algorithms. We use a graph theoretic approach to obtain thedoi:10.1109/twc.2010.07.090897 fatcat:3ufitnb2orf23cmpb63ic7o2gm
