An Effective Resource Allocation Strategy for Three-Layer Networks

The unbalance of resource allocation often confines the traffic capacity of network. The limitation of network resources highlights the necessity of rational allocation of network resources. In this brief, a resource allocation strategy based on node degree is proposed for three-layer network with different speed physical layers. Through simulation comparison, the traffic capacity of proposed strategy is about 1.5 times that of the average allocation strategy, and the reduction rate of total load can reach more than 60%. In addition, assigning appropriate delivery capacity to nodes reduces the average traveling time. Finally, through the proposed load-related indicators, the traffic load distribution comparison can be intuitively obtained.
