The scarcity of mobile broadband spectrum is a problem hurting all stakeholders in the mobile landscape -- mobile operators (MOs), content providers, and mobile users. Building additional capacity is expensive, and MOs are reluctant to make such ...

The current architecture supporting data services to mobile devices is built below the network layer (IP) and users receive the payload at the application layer. Between them is the transport layer that can cause data consumption inflation due to the ...

Smartphones have emerged as a popular and frequently used platform for the consumption of multimedia. New display technologies, such as AMOLED, have been recently introduced to smartphones to fulfill the requirements of these multimedia applications. ...

Wi-Fi is the most prominent wireless network interface in current smart devices. Due to its high power consumption, Power Saving Mode (PSM) schemes have been proposed to reduce power consumption. We show how the current popular PSM schemes implemented ...

Achieving perfect power proportionality in current mobile devices is not enough to prevent users from running out of battery. Given a limited power budget, we need to control active power usage, and there needs to be a prioritization of activities. In ...

This paper envisions a new research direction that we call psychological computing. The key observation is that, even though computing systems are missioned to satisfy human needs, there has been little attempt to bring understandings of human need/...

Wearable cameras and displays, such as the Google Glass, are around the corner. This paper explores techniques that jointly leverage camera-enabled glasses and smartphones to recognize individuals in the visual surrounding. While face recognition would ...

Due to limited processing capability, contemporary smartphones cannot extract frequency domain acoustic features in real-time on the device when the sampling rate is high. We propose a solution to this problem which exploits the sparseness in speech to ...

Mobile crowdsensing is becoming a vital technique for environment monitoring, infrastructure management, and social computing. However, deploying mobile crowdsensing applications in large-scale environments is not a trivial task. It creates a tremendous ...

Open Data Kit (ODK) is an open-source, modular toolkit that enables organizations to build application-specific information services for use in resource-constrained environments. ODK is one of the leading data collection solutions available and has been ...

We study the competing goals of utility and privacy as they arise when a user shares personal sensor data with apps on a smartphone. On the one hand, there can be value to the user for sharing data in the form of various personalized services and ...

The display cloud model allows users to select local and remote programmable displays, and add them to a user specific cloud display where the user can arrange them freely. On a cloud display, the abstraction representing remote graphical content is ...

The mobile computing experience would improve if users could switch seamlessly from one device to another, with both data and computation state preserved across the switch without apparent delay. This paper proposes VMsync, a system for synchronizing ...

Web access on mobile platforms already constitutes a significant (> 20%) share of web traffic [3]. Furthermore, this share is projected to even surpass access from laptops and desktops [11]. In conjunction with this growth, user expectations for the ...

We explore the use of TV whitespaces based communication systems for providing robust connectivity to vehicles. We envision a setup where whitespaces base stations mounted by roadside that communicate with whitespaces gateway nodes placed on vehicles. A ...

In this paper, we propose a Social Vehicle Navigation system that integrates driver-provided information into a vehicle navigation system in order to calculate personalized routing. Our approach allows drivers registered into certain vehicle social ...

Ride-sharing on the daily home-work-home commute can help individuals save on gasoline and other car-related costs, while at the same time reducing traffic and pollution in the city. Work in this area has typically focused on technology, usability, ...
