Energy-Limited Wireless Networking with Directional Antennas: The Case of Session-Based Multicasting
15 years 8 months ago
— We consider ad hoc wireless networks that use directional antennas and have limited energy resources. The performance objectives of such networks depend largely on the applicat...
