One_D groundwater flow equation by Meshfree methods

I am a new Ph.D student. I want to solve 1-D transient flow equation with Dirichlet B.C.by meshfree method(Point collocation) with MQ-RBF (q=0.5).I've taken 11 nodes in a domain with 5 nodes in the support domain.How to take 5 nodes for 1st,2nd,10th and 11th node?How shape parameter α(alpha) is to be considered?
