Written by leading authorities in the field, Enhancing the Performance of Ad Hoc Wireless Networks with Smart Antennas presents an overview of basic MAC and routing protocols in ad hoc networks and presents the strategies and techniques used in designing MAC and routing protocols for improved medium utilization and improved routing performance with effective load balancing using smart antennas. It addresses some of the design issues related to priority-based QoS routing protocols with smart antennas to illustrate the potential of these antennas in relation to omni-directional antennas in the context of ad hoc network. Other discussions explore open problems and challenges in the field.
