The mobile space has witnessed a surge in the number of handheld wireless devices as well as the number of mobile applications over the past few years. Mobile applications that are used in various domains, e.g., entertainment, transportation, education, homeland security and etc, generate an enormous amount of global mobile data traffic delivered over wireless networks. While infrastructure networks (WiFi, 3G/4G) are widely used and can support long distance content delivery, they may be expensive (cellular data plans) and their availability anytime, anywhere (e.g., WiFi) is often limited. Ad hoc networks, e.g., Bluetooth, WiFi Direct, occasionally used to deliver content, are inexpensive and easily deployed; however, they can deliver content only to devices in close proximity. These network technologies are also limited in their abilities to deliver rich content at scale; the presence of additional multiQoS needs, e.g. timeliness, reliability further increases complexity. In this thesis, we explore hybrid network approaches for mobile data delivery that augment infrastructure networks with opportunistic use of ad hoc networks. Challenges in effective use and deployment of such hybrid infrastructure and ad hoc networks arise due to the unreliable nature of the wireless medium, user mobility, limited resources on mobile devices and reluctance of users to share network access. In this thesis, we explore the use of hybrid networks in a range of popular mobile applications in (a) cooperative settings (where users are willing to participate in delivering data) and non-cooperative settings (where users lack incentives to participate in the data delivery process) and develop solutions addressing challenges in both environments.

The mobile space has witnessed a surge in the number of handheld wireless devices as well as the number of mobile applications over the past few years. Mobile applications that are used in various domains, e.g., entertainment, transportation, education, homeland security and etc, generate an enormous amount of global mobile data traffic delivered over wireless networks. While infrastructure networks (WiFi, 3G/4G) are widely used and can support long distance content delivery, they may be expensive (cellular data plans) and their availability anytime, anywhere (e.g., WiFi) is often limited. Ad hoc networks, e.g., Bluetooth, WiFi Direct, occasionally used to deliver content, are inexpensive and easily deployed; however, they can deliver content only to devices in close proximity. These network technologies are also limited in their abilities to deliver rich content at scale; the presence of additional multiQoS needs, e.g. timeliness, reliability further increases complexity. In this thesis, we explore hybrid network approaches for mobile data delivery that augment infrastructure networks with opportunistic use of ad hoc networks. Challenges in effective use and deployment of such hybrid infrastructure and ad hoc networks arise due to the unreliable nature of the wireless medium, user mobility, limited resources on mobile devices and reluctance of users to share network access. In this thesis, we explore the use of hybrid networks in a range of popular mobile applications in (a) cooperative settings (where users are willing to participate in delivering data) and non-cooperative settings (where users lack incentives to participate in the data delivery process) and develop solutions addressing challenges in both environments.

In the cooperative environment, we first develop a hybrid network protocol (HybCAST) for the problem of reliable and fast rich content delivery in mission-critical scenarios from a content server to mobile users. HybCAST employs clustering techniques to structure the hybrid network into overlays that maintain stability under device mobility. Data delivery over the clustering structure occurs via a push-pull mechanism where content is first pushed (for speed) and then selectively pulled (for reliability), using a combination of broadcast and unicast. HybCAST achieves 100\% reliable delivery with 5x improvement in speed and has been implemented on the Android platform. We next explore the problem of massive video streaming to mobile users (e.g., live sporting events) using hybrid networks - our approach here utilizes data characteristics and dependency in layered video content to support quality-aware and timely delivery of video content. We formulate hybrid network video streaming as an optimization problem, design simple and effective heuristics; a practical variant of these heuristics has been implemented and validated on Android phones. Our experiments show a 10 fold improvement in scalability (i.e. the number of users who can receive high quality mobile video).

In the non-cooperative environment, we design a crowdsourcing solution, CrowdMAC, that incentivizes mobile users to participate in the hybrid network data distribution by sharing their data plans with other users. CrowdMAC enables the creation of an open marketplace in which users can sell available quotas on their data plans to buyers in close proximity. CrowdMAC utilizes the Lyapunov optimization framework to design a family of techniques - specifically, admission control mechanisms at the seller (also known as mobile hotspot) and hotspot selection techniques at the buyer (i.e., mobile client) end that can ensure stability (no queue overflows). To provide delay guaranteed rich data delivery, CrowdMAC implements a multihoming technique that exploits multipath data transmission by hiring more than one hotspot to deliver content. CrowdMAC has been successfully implemented and evaluated on an Android testbed and using simulation studies. In summary, hybrid infrastructure and ad hoc networks that enable sharing/crowdsourcing of wireless access can create new opportunities to significantly expand the scale and scope of mobile data delivery just as VoIP has changed the landscape of telephony today.
