Table 1 Basic algorithm

   - Annulus number is set to i when b_i-1≤ R ≤ b _i (b _k for k = 1,...,i is obtained from Equation (5))

   - For each node n in annulus j = 1..i,

Transmission is provided by a j-hop transmission. Transmission range of node is adjusted based on $\frac{\mathsf{\text{R}}}{\mathsf{\text{j}}}$
