Data collection for mobile crowdsensing in the presence of selfishness
Mobile crowdsensing is an emerging approach to data collection by exploiting the sensing abilities offered by smart phones and users' mobility. Data collection can be implemented by exploiting the forwarding opportunities given by the contacts between nodes. However, as cell phones are still resource constrained, most people are socially selfish so that they may not always cooperate with each o...
متن کاملOptimal Data Partitioning and Forwarding in Opportunistic Mobile Networks
In opportunistic mobile networks, existing schemes rely on the assumption that data can be entirely transmitted at each contact. However, in an opportunistic mobile network, the transmission probability exponentially decreases as the data size increases. That is, the contact duration in each contact might be insufficient to deliver large data. Therefore, it is reasonable to partition original d...
متن کاملData-Centric Mobile Crowdsensing
Mobile crowdsensing (MCS) is a promising sensing paradigm that leverages the diverse embedded sensors in massive mobile devices. A key objective in MCS is to efficiently schedule mobile users to perform multiple sensing tasks. Prior work mainly focused on interactions between the task-layer and the user-layer, without considering tasks’ similar data requirements and users’ heterogeneous sensing...
متن کاملOptimal Cellular Traffic Offloading Through Opportunistic Mobile Networks by Data Partitioning
In cellular traffic offloading through opportunistic mobile networks, existing schemes rely on the assumption that data can be entirely transmitted at each contact. However, transmission probability exponentially decreases as data size increases. That is, the contact duration in each contact might be insufficient for delivering large data. The objective of this paper is to find an optimal traff...
متن کاملIncentives for Delay-Constrained Data Query and Feedback in Mobile Opportunistic Crowdsensing
In this paper, we propose effective data collection schemes that stimulate cooperation between selfish users in mobile opportunistic crowdsensing. A query issuer generates a query and requests replies within a given delay budget. When a data provider receives the query for the first time from an intermediate user, the former replies to it and authorizes the latter as the owner of the reply. Dif...
