{{Main|Node influence metric}}
Limitations to centrality measures have led to the development of more general measures.
Two examples are
the '''accessibility''', which uses the diversity of random walks to measure how accessible the rest of the network is from a given start node,<ref name="Travencolo2008">{{ cite journal| last1=Travençolo |first1=B. A. N. |last2=da F. Costa| first2 =L.| title=Accessibility in complex networks| journal=Physics Letters A| year=2008|volume=373|issue=1|pages=89–95 |doi=10.1016/j.physleta.2008.10.069 |bibcode=2008PhLA..373...89T }}</ref>
and the '''expected force''', derived from the expected value of the [[force of infection]] generated by a node.<ref name="Lawyer2015"/>
Both of these measures can be meaningfully computed from the structure of the network alone.
