A Routing Protocol for Resource Scheduling in Wireless Networks Using Directional Antennas

With the continued increase of speed and capacities of computing devices and the growing needs of people for mobile computing capabilities, multihop wireless networks have gained a lot of interest from the research community. Quality of service (QoS) provisioning in these networks is an essential component that is needed to support multimedia and real-time applications. On the other hand, directional antenna technology provides the capability for considerable increase in spatial reuse which is essential in the wireless medium. In this paper, a bandwidth reservation protocol for QoS routing in TDMA-based multihop wireless networks using directional antennas is presented. The routing algorithm allows a source node to reserve a path to a particular destination with the needed bandwidth which is represented by the number of slots in the data phase of the TDMA frame. Further optimizations to improve the efficiency and resource utilization of the network are provided.
