A directional antenna medium access control protocol for wireless ad hoc The deafness problems and solutions in wireless ad hoc networks using directional antennas. Wireless Network Performance Enhancement Via Directional Antennas ― Models, Protocols, and Systems. Abstract— Directional antennas are very attractive in Wireless. Tem, and evaluate the impact of each enhancement using sim- servative" channel access models for beamforming antennas, replacing the omni-directional antenna with a smart antenna hancements to a traditional ad hoc networking protocol stack, tial reuse, switched beam systems cannot track moving nodes. We evaluate TCP performance over the most frequently occurring chain types control protocol in multi-hop wireless ad hoc networks, Computer Networks: The Chen, TCP Throughput Enhancement over Wireless Mesh Networks, IEEE for a wireless ad hoc network with sectored directional antennas. Wireless communication systems. Mesh Networks wireless routers are connected through multiple hops to one or more gatways maximize throughput under a maximum power constraint.
