  Kagome-lattice crystal is crucial in quantum materials research, exhibiting
unique transport properties due to its rich band structure and the presence of
nodal lines and rings. Here, we investigate the electronic transport properties
and perform first-principles calculations for Ni$_{3}$In$_{2}$Se$_{2}$ kagome
topological semimetal. First-principle calculations indicate six endless Dirac
nodal lines and two nodal rings with a $\pi$-Berry phase in the
Ni$_{3}$In$_{2}$Se$_{2}$ compound. The temperature-dependent resistivity is
dominated by two scattering mechanisms: $s$-$d$ interband scattering occurs
below 50 K, while electron-phonon ($e$-$p$) scattering is observed above 50 K.
The magnetoresistance (MR) curve aligns with the theory of extended Kohler's
rule, suggesting multiple scattering origins and temperature-dependent carrier
densities. A maximum MR of 120\% at 2 K and 9 T, with a maximum estimated
mobility of approximately 3000 cm$^{2}$V$^{-1}$s$^{-1}$ are observed. The Ni
atom's hole-like d$_{x^{2}-y^{2} }$ and electron-like d$_{z^{2}}$ orbitals
exhibit peaks and valleys, forming a local indirect-type band gap near the
Fermi level (E$_{F}$). This configuration enhances the motion of electrons and
holes, resulting in high mobility and relatively high magnetoresistance.
