However, the premise of communication is connectivity. ❑ In large scale wireless network with unreliable links, it is too costly to maintain full connectivity. Therefore, we consider a slightly weaker connectivity-connectivity in percolation sense. ➢ Random Connection Model (RCM) ➢ Instantaneous and Long-term Connectivity ➢ Instantaneous Critical Density ( ) and Long-term Critical Density ( ) I  L Fundamental Relationship between Node Density and Delay in Wireless Ad Hoc Networks with Unreliable Links
