In real life, people usually have a herd mentality. This paper studies the influence of herd mentality mechanism on the dynamical behaviors of rumor spreading, and proposes a novel susceptible-infected-removed (SIR) model. Based on the mean-field theory, both the critical threshold of the homogeneous networks and the final rumor size are investigated. Theoretical analysis and numerical simulation...
Cooperative spectrum sharing can effectively improve the spectrum usage by allowing secondary users (SUs) to dynamically and opportunistically share the licensed bands with primary users (PUs). In return, an SU will relay a PU's traffic to improve the PU's effective data rate. In this paper, we study how one PU and one SU achieve an efficient spectrum sharing through dynamic noncooperative bargaining...
This research establishes an analytical model of the capacity allocation process, where the enterprise pursues maximum total customer value subject to the limited customization costs and adjustment costs. It is well-known that the less the discrepancy between customer requirements and enterprise offerings, the higher customer-perceived value is. Therefore, the optimization objective of the analytical...
