In this paper, we consider joint pricing and task allocation in a unified mobile crowdsensing system, where all initiators users are viewed as peers. From an exchange market point of view, the such system depend only on supply demand since no one can dominate process, with optimal solution being characterized by Walrasian equilibrium. This is quite different from existing approaches, each initiator builds specific provides incentive mechanism to maximize his/her own utility. We design...

The performance and effectiveness of a vehicle platoon rely on the topology information flow quality communications, such as delays dropouts.

Maximum consensus is useful in many applications such as leader selection and time synchronization, it advantageous for its decentralization finite convergence. However, without preservation mechanisms maximum consensus, nodes' initial states especially the identity of node with state will be disclosed, which undesirable some application scenarios. To preserve privacy while maintaining advantages, we propose a Privacy Preserving Consensus (PPMC) algorithm, where all nodes independently...

Abstract This paper presents an adaptive tube‐based stochastic model predictive control algorithm for linear systems with state‐dependent additive uncertainties. Specifically, the uncertainty of system is modeled using Gaussian process regression, and information predicted by regression online leveraged to establish a confidence region uncertainty. By employing this region, time‐varying probabilistic reachable set, referred as tube, computed. Subsequently, process‐based devised set redefine...
