The Heavy Tailed (HT) traffic from wireless users, caused by the emerging Internet and multimedia applications, introduces a HT interference region within which network users will experience unbounded delay with infinite mean and/or variance. Specifically, it is proven that, if the network traffic of primary networks (e.g., cellular and Wi-Fi networks) is heavy tail distributed, there always exists a critical density? such that, if the density of primary users is larger than ?p, the secondary network users (e.g., sensor devices and cognitive radio users) can experience unbounded end-to-end delay with infinite variance even though there exists feasible routing paths along the network users.
