A novel directional-NAV-based packets scheduling algorithm for ad hoc networks

Head of Line (HOL) blocking is one of the new challenges in the smart antenna system in wireless ad hoc networks. To address the problem, this paper proposes a novel Directional Network Allocation Vector-based Packets Scheduling (DBPS) algorithm. The algorithm gains greater throughput and is more suitable to the dynamic network topology than other methods. The simulation and performance analysis show that the HOL blocking problem can be solved efficiently and higher throughput can be achieved via the proposed algorithm.
