Let be a vertex of a connected simple graph and be a pair of vertices in G. let ) be the distance between and A vertex is said to resolve and if . A set of vertices W of G is called a settling set of Gif every pair of vertices resolved by atleast one vertices . A settling set of G with least cardinality is called metric premise of G. The cardinality of metric premise is called metric index of G. In this paper metric index of oxide network is investigated. Catchphrases: Metric premise ,Metric index ,Oxide network, Interconnection Network.
