  The dynamics of tripartite entanglement of fermionic system in noninertial
frames through linear contraction criterion when one or two observers are
accelerated is investigated. In one observer accelerated case the entanglement
measurement is not invariant with respect to the partial realignment of
different subsystems and for two observers accelerated case it is invariant. It
is shown that the acceleration of the frame does not generate entanglement in
any bipartite subsystems. Unlike the bipartite states, the genuine tripartite
entanglement does not completely vanish in both one observer accelerated and
two observers accelerated cases even in the limit of infinite acceleration. The
degradation of tripartite entanglement is fast when two observers are
accelerated than when one observer is accelerated. It is shown that tripartite
entanglement is a better resource for quantum information processing than the
bipartite entanglement in noninertial frames .
