Constructing Internet Plus New Infrastructure in Cities

Constructing cities, deconstructing scaling laws

Cities can be characterized and modelled through different urban measures. Consistency within these observables is crucial in order to advance towards a science of cities. Bettencourt et al. have proposed that many of these urban measures can be predicted through universal scaling laws. We develop a framework to consistently define cities, using commuting to work and population density threshol...

Energy Efficient Internet Infrastructure

Internet is built as a packet-switching network. The kernel function of Internet infrastructure, including routers and switches, is to forward the packets that are received from one subnet to another subnet. The packet forwarding is accomplished by using the header information extracted from a packet to look up the forwarding table maintained in the routers/ switches. Due to rapid growth of net...

Internet Multicast Routing Infrastructure

This is a proposal for research in the area of distributed multicast routing algorithms. It is based on prior work done in support of DNCRI programs, including those in the areas of network time synchronization, network routing algorithms. and in support of DARPA collaborative programs with the DARTnet and CAIRN projects and in other research areas represented by the proposers. The proposed wor...

Green infrastructure for cities: The spatial dimension

Planning for sustainable cities is a complex process addressing the fundamental areas of economic, environmental and socially-equitable sustainability. This chapter focuses on the environmental area, with theories, models, and applications illustrating possible spatial configurations of a green infrastructure to support ecological and physical processes in the built environment including: hydro...
