摘要
Portable sensory devices such as sensors equipped mobile phones enable convenient sensing and monitoring of urban areas Such devices which are always carried by humans are referred to as Human Probes Instead of carrying out sensing activities independently cooper anon of Human Probes helps in realizing efficient urban sensing environments In this paper we propose an Architecture of Qualitative Urban In formation Blending and Acquisition (Aquiba) in which the sensing activities are adjusted autonomously according to cooperation of Human Probes Aquiba introduces a cooperative sensing approach which aims to maintain desired sensing resolution efficiently while minimizing overall energy con sumption To study the performance of Aquiba we have conducted corn prehensive simulations ranging from small to large scale scenarios along with applying three different movement patterns of human The simulation results demonstrate that Aquiba is capable of providing high sensing resolution and reducing overall energy consumption
