Wormhole modeling in general relativity

In this paper, the traversable wormhole solutions are investigated for Einstein's field equations with cosmological constant. Using redshift function \Phi(r) and shape function b(r) as \Phi(r)=-1/r^2 and $b(r)=\frac{r_0\log(r+1)}{\log(r_0+1)}$ in the static and spherically symmetric metric of wormholes, the spherical regions are determined where the energy conditions are satisfied for positive value of cosmological constant.
