We study a three-dimensional network of Josephson junctions in a magnetic field, which undergoes a first-order melting transition of the triangular vortex lattice. We perform a Langevin dynamics calculation of the resistance and current-voltage ({ital I}{minus}{ital V}) characteristics. We find hysteresis in the resistance as a function of temperature as measured in untwinned YBa{sub 2}Cu{sub 3}O{sub 7}. Close to the melting temperature the {ital I}{minus}{ital V} curves are {ital {ital S}} shaped with hysteresis and show a melting transition when {ital increasing} {ital the} {ital current}, driven by the blowing out of current nucleated vortex loops. {copyright} {ital 1995 The American Physical Society.}
