Abstract: The weapon cooperation data link adopts hierarchical methodology generally, as the nodes in it are numerous and moving rapidly. In the battlefield, the interference often occurs, and it will impact the delay seriously, which is an important parameter of the network. Morcover,thc general approaches that only care about the delay of next hop can't always obtain the minim end-to-end delay. A delay oriented routing approach with implementing model was proposed for backbones. The SINR to the neighboring nodes and the end-to-end delay to the destination could be obtained to be used for deciding upon the next hop adopting the idea of feedback and cross-layer. The results provide important insights that the approach can get better performance than other several typical routing protocols.
