| k | degree of a subpopulation, i.e. number of connectionsto other subpopulations | |
| P(k) = k-γ;γ | subpopulation degree distribution; power-law exponent | γ = 2.3,3 |
| V;V k | total number of subpopulations; number of subpopulationswith degree k | V = 104 |
| average population of a node, population of a node; | ||
| with degree k | ||
| ϕ; | power-law exponent; | ϕ = 3/4 |
| w 0 | mobility scale | w0 = 0.05 |
| number of travelers from a subpopulation with degree k l | ||
| w lm = w0(k l k m )θ; | to a subpopulation with degree k m ; | |
| θ | power-law exponent | θ = 0.5 |
