On the Design of Campus Parking Systems With QoS Guarantees

Abstract

Parking spaces are resources that can be pooled together and shared, especially when there are complementary day-time and night-time users. We answer two design questions. First, given a quality of service requirement, how many spaces should be set aside as contingency during day-time for night-time users? Next, how can we replace the first-come-first-served access method by one that aims at optimal efficiency while keeping user preferences private?

Distributed Ledger Technology for Smart Cities, the Sharing Economy, and Social Compliance

“…More generally, techniques to enforce compliance with social contracts are a fundamental part of any sharing economy system. The design of shared systems is both topical from a practical and theoretical perspective [5], [6]. Analytic issues associated with developing parctical sharing systems include the following basic questions.…”

Stochastic Frequency Control of Grid-Connected Microgrids

“…In this way, it is possible to take into account the different needs of single MGs, namely, their utility functions. It can be proven that the unsynchronized version of the AIMD can be used to obtain convergence of the long-term average state to the optimal point of a particular class of optimization problems, called optimal resource allocation problems [18]. In particular, if we consider the long-term average of the state variables P si (t)…”

“…For further details on this subject we refer the interested reader to [18] and [33]. Finally, both centralized and decentralized versions of AIMD may be implemented, depending on whether global or local frequencies are used to give rise to CEs:…”

“…The rationale for a stochastic approach, as opposed to a deterministic one, is that the latter would require heavy communication, either among the many MGs or through a centralized base station, in order to be effective. This requirement, besides the obvious economic disadvantages and robustness issues [17], might also give rise to privacy concerns [18].…”

“…• The unsynchronized Addictive Increase Multiplicative Decrease (AIMD) algorithm [18] is used for the first time in this context to mitigate the negative effects of the penetration of MGs on the frequency deviation of the transmission system.…”
