Abstract :
Lifetime of multicast connection in a wireless ad-hoc network is constrained by routing topology as well as mobility, interference, noise and battery capacity. In order to optimize the multicast lifetime, a series of routing algorithms and cognitive network models with directional antennas have been proposed. However, these methods can only reach a sub-optimal level. In this paper, we propose an additional search in a specific beamwidth space. Simulation results show that the Beamwidth Scanning algorithm can pick up routing topologies which correspond to improved multicast lifetime.
