Enhancing network transmission capacity by efficiently allocating node capability

TL;DR

This paper presents a practical node-capability allocation scheme that significantly boosts network transmission capacity by redistributing node capabilities based on local connectivity, especially in heterogeneous networks.

Contribution

It introduces a novel, locally-informed capability allocation method that improves transmission capacity without increasing total node capability.

Findings

Transmission capacity increased by two orders of magnitude.

Scheme is effective for networks with heterogeneous structures.

Enhancement achieved through redistributing existing node capabilities.

Abstract

A network's transmission capacity is the maximal rate of traffic inflow that the network can handle without causing congestion. Here we study how to enhance this quantity by redistributing the capability of individual nodes while preserving the total sum of node capability. We 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. We show the scheme enhances the transmission capacity by two orders of magnitude for networks with heterogenous structures.
