An OSPF Based Backhaul Protocol for 5G Millimeter Wave Network

This paper proposes an Open Shortest Path First (OSPF) based Backhaul Protocol for 5th Generation (5G) mobile communication millimeter wave network (OBPG). This protocol includes the establishment stage and the transmission stage of the millimeter wave backhaul network. During the establishment stage, all millimeter wave micro base stations use fixed time division. The method is based on the OSPF protocol to establish the backhaul path between millimeter wave micro base stations. In the transmission stage, based on the network topology formed by millimeter wave micro base stations, the coloring method is used to allocate data transmission time slots. After that, the micro base station polls and schedules users for data transmission in the allocated data transmission time slot. The simulation results show that when the blocking probability of the millimeter-wave directional link is 30 %, and along with the number of multiple associations between users and millimeter-wave micro base stations increases, the network throughput performance is about 20 % higher than the performance of the number which is one less.
