SUMMARYThe 3G and Beyond 3G wireless networks introduce new technologies, and in many cases, new frequency bands. Integrated hierarchical network architectural studies suggest that by using a Common Radio Resource Manager to engineer traffic across these component networks, operators can achieve increased efficiency and flexibility in supporting changing traffic demands. This study demonstrates how vertical handovers can be used to optimize network performance, by adaptively rearranging traffic across network boundaries. We survey policy implementations that consider which services/sessions shall move, where they shall move, when they shall move, and whether they shall return.

Information security regulation is coming of age, with regulation very recently being passed in emerging economies. Developed nations have stable regulation, whose implementation and effectiveness can now be evaluated. This paper evaluates security regulation across both these developed and emerging economies, across four continents and six nations: China, India, Indonesia, Brazil, Germany, and the United States. We find national security regulations may be comprehensive or piecemeal; strategic or tactical in implementation; and developed in reactionary or proactive fashions.
