Enhancing Network Transmission Capacity by Efficiently Allocating Node Capability
A network's transmission capacity is the maximal rate of traffic inflow that the network can handle without causing congestion. Here the authors study how to enhance this quantity by redistributing the capability of individual nodes while preserving the total sum of node capability. They propose a practical and effective node-capability allocation scheme which allocates a node's capability based on the local knowledge of the node's connectivity. They show the scheme enhances the transmission capacity by two orders of magnitude for networks with heterogenous structures.
