Dynamic traffic prioritization scheme for multihop tactical networks

Multihop tactical network applications require that mission-critical data should be guaranteed to be delivered to their corresponding targets in time. However, end-to-end QoS (Quality of Service) assurance in multihop networks is a very challenging topic. Several schemes have been proposed to provide end-to-end delay assurance for multihop wireless network environment. However, these schemes do not consider the situation that the network is overloaded and burst collision is occurred. In this paper, we propose the dynamic traffic prioritization scheme for multihop tactical networks. The proposed scheme dynamically assigns priorities to traffic according to network status and the newly defined traffic categories in order to achieve guaranteed end-to-end QoS in multihop tactical networks. In addition, when the burst collision is occurred, the proposed scheme satisfies the requirement of mission-critical data by sacrificing the QoS requirement of non-mission-critical data.
