Tailoring group membership consistency for mobile networks

Mobility and intermittent connectivity inject inaccuracy in determining group membership and exacerbate the time required to agree on the current group membership. In this paper, we present a group membership service based on partial member connectivity that allows members to agree on a shared approximation of the group membership based on local neighborhood connectivity. In particular, the consistency needs provided by the application determine the degree of consistency of the membership service and allow the membership service to tailor the neighborhood service in terms of fidelity ratio and time detection period.
