“…Other common criteria such as device resource/status may be further considered when selecting the mainstay. Still, our evaluation does not analyze the power consumption due to D2D communication, as we rely on the results of previous studies that show that D2D networking is cheaper than cellular networking [2,5,34]. It is part of our future work to further investigate the overall effectiveness of IAM in terms of resource efficiency vs data accuracy, compared to the centralized approach.…”

“…At the same time, P2P wireless ad hoc network technology (e.g., Wi-Fi Direct) enables the discovery of nearby mobile devices and the exchange of data between peers, making the collaboration possible [6,20]. Some crowdsensing systems already exploit the P2P collaboration of crowdsensors as they meet [5,34,39]. However, the collaboration primarily deals with handling the relay of data, while deployed static edge servers are in charge of the distributed data aggregation.…”

Crowdsensing allows citizens to contribute to the monitoring of their living environment using the sensors embedded in their mobile devices, e.g., smartphones. However, crowdsensing at scale involves significant communication, computation, and financial costs due to the dependence on cloud infrastructures for the analysis (e.g., interpolation and aggregation) of spatio-temporal data. This limits the adoption of crowdsensing by activists although sorely needed to inform our knowledge of the environment. As an alternative to the centralized analysis of crowdsensed observations, this paper introduces a fully distributed interpolation-mediated aggregation approach running on smartphones. To achieve so efficiently, we model the interpolation as a distributed tensor completion problem, and we introduce a lightweight aggregation strategy that anticipates the likelihood of future encounters according to the quality of the interpolation. Our approach thus shifts the centralized postprocessing of crowdsensed data to distributed pre-processing on the move, based on opportunistic encounters of crowdsensors through state-of-the-art D2D networking. The evaluation using a dataset of quantitative environmental measurements collected from 550 crowdsensors over 1 year shows that our solution significantly reduces -and may even eliminate-the dependence on the cloud infrastructure, while it incurs a limited resource cost on end devices. Meanwhile, the overall data accuracy remains comparable to that of the centralized approach.

“…Crowdsourced wireless community networks which are composed of shared Wi-Fi APs were investigated in [14]- [16] to alleviate the limited coverage problem of Wi-Fi APs. UPN mechanisms have been investigated to utilize the power of wide-spread movable terminals [17]. A reimbursing scheme was proposed in [18] for enabling a mobile virtual network operator to offer free data quota as incentives.…”

Device-to-Device (D2D) communication is a promising solution in next generation cellular technologies to efficiently provide on-demand connectivity. Among existing D2D communication schemes, the outband approach that uses unlicensed spectrum can eliminate the spectrum interference with cellular links. Although the autonomous outband is a strong option because of its simple operation, it is a significant problem to appropriately encourage the participation of mobile users. To address this issue, this paper proposes a gamified participatory D2D (GP-D2D) communication where mobile users compete their gain that is obtained through providing network connectivity for other mobile users. The contribution of this work is to propose a novel approach of the autonomous outband D2D communication for efficiently encouraging the active participation of mobile users. The feasibility of the proposed gamified approach is confirmed with theoretical analysis and computer simulations. It is implied from the results that gamification is an effective approach for autonomous D2D communication by defining appropriate game-settings such as gain mechanisms.

“…Such commoditization is often accompanied by default admin accounts, guest accounts, default disabled security settings, etc, that result in little to no security for the device and the information. While both fixed and mobile hotspots [6] are in use, in this paper, we specifically focus on static hotspots.…”

VOUCH-AP: privacy preserving open-access 802.11 public hotspot AP authentication mechanism with co-located evil-twins

Open-access 802.11 public Wi-Fi hotspots have become a basic necessity for hundreds of millions of mobile users' persistent on-the-go access to the Internet. 802.11 Wi-Fi networks are designed and deployed to support rudimentary low-level authentication at the link layer enabling an AP to decide whether to allow a client to associate. Similar authentication mechanisms are not provisioned for the clients. Hence, there is a fundamental information asymmetry at play in an 802.11 public hotspot, which tilts the balance in favor of an adversary intending to launch AP-based evil-twin attacks. Furthermore, link-layer authentication has little security since the link itself is completely open to numerous attacks. In this paper, we address this information asymmetry problem and propose a simple yet powerful solution for identifying and eliminating malicious APs, thereby providing users safe and private 802.11 public hotspots. Our proposed AP authentication framework is called VOUCH-AP, a portable and platform-independent solution. VOUCH-AP is, to the best of our knowledge, the first work to consider digital certificate based AP authentication. VOUCH-AP makes use of a modified version of a X.509 digital certificate consisting of additional fields for provisioning robust security and privacy to counter evil-twin attacks. The proposed solution does not require any hardware upgrades or specialized hardware, unlike 802.11i (aka WPA2). Finally, through security analysis, we show the security robustness of the proposed VOUCH-AP framework to counter evil-twin attacks.
