Research of the Routing Strategy under the Constraint of Privileged Load in Complex Networks

there are loads with different properties in the real network, such as a small number of ambulances, express mail and other special loads in the transportation network and logistics network. This kind of load that defined as privileged load with higher real-time requirements introduced into the complex network. Combined with the reality that the existing routing strategies cannot meet the privileged load network, we improve the existing traffic model. We establish the privileged load network model. On the premise that the nodes give priority to the privileged load, we deduce the key parameters affecting the transmission capacity through theoretical derivation. Around this parameter, we propose a complex network routing optimization strategy for privileged load. Finally, we use MATLAB simulate the proposed routing strategy and compared with the existing classical routing strategy. The experimental results show that the routing strategy proposed in this paper maximizes the overall transmission capacity of the network on the premise of ensuring the real-time transmission of privileged load.
