Summary:In this paper, we study the temporal correlation of interference in mobile ad-hoc networks under a correlated shadowing environment. By modeling the node locations as a 1-D Poisson point process with an i.i.d. mobility model and considering spatially correlated shadowing that depends on the distance between nodes, we derive a simple asymptotic expression of the temporal correlation coefficient of interference as the variance of log-normal shadowing increases. This shows a readable relationship between the correlation distance of lognormal shadowing and the temporal correlation of interference and thus can be useful for modeling general wireless systems with spatially correlated shadowing.
