# Diffusion Degree

#### Definition

The degree centrality of node v can be defined as:

- σ(u
_{i}, v) = 1 if and only if u_{i}and v are connected and = 0 otherwise.

_{v}, can activate its neighbor u with probability λ_{v}. So, considerable contribution of node v in the diffusion process is:_{DD}of node v as:#### References
