RADAR: an in-building RF-based user location and tracking system
TLDR
RADAR is presented, a radio-frequency (RF)-based system for locating and tracking users inside buildings that combines empirical measurements with signal propagation modeling to determine user location and thereby enable location-aware services and applications. Expand
MAUI: making smartphones last longer with code offload
TLDR
MAUI supports fine-grained code offload to maximize energy savings with minimal burden on the programmer, and decides at run-time which methods should be remotely executed, driven by an optimization engine that achieves the best energy savings possible under the mobile device's current connectivity constrains.

The Case for VM-Based Cloudlets in Mobile Computing
TLDR
The results from a proof-of-concept prototype suggest that VM technology can indeed help meet the need for rapid customization of infrastructure for diverse applications, and this article discusses the technical obstacles to these transformations and proposes a new architecture for overcoming them.

A rate-adaptive MAC protocol for multi-Hop wireless networks
TLDR
This paper presents a rate adaptive MAC protocol called the Receiver-Based AutoRate (RBAR) protocol, based on the RTS/CTS mechanism, which can be incorporated into many medium access control protocols including the widely popular IEEE 802.11 protocol. Expand
SSCH: slotted seeded channel hopping for capacity improvement in IEEE 802.11 ad-hoc wireless networks
TLDR
A link-layer protocol called Slotted Seeded Channel Hopping, or SSCH, is presented that increases the capacity of an IEEE 802.11 network by utilizing frequency diversity and uses a novel scheme for distributed rendezvous and synchronization. Expand
A multi-radio unification protocol for IEEE 802.11 wireless networks
TLDR
The results show that under dynamic traffic patterns with realistic topologies, MUP significantly improves both TCP throughput and user perceived latency for realistic workloads. Expand
Mobility modeling, location tracking, and trajectory prediction in wireless ATM networks
TLDR
A hierarchical user mobility model is developed that closely represents the movement behavior of a mobile user and that, when used with appropriate pattern matching and Kalman filtering techniques, yields an accurate location prediction algorithm, HLP, or hierarchical location prediction, which provides necessary information for advance resource reservation and advance optimal route establishment in wireless ATM networks.

A case for adapting channel width in wireless networks
TLDR
This work quantifies the impact of channel width on throughput, range, and power consumption, and presents a channel width adaptation algorithm, called SampleWidth, based on a simple search process that builds on top of existing techniques for adapting modulation. Expand
MultiNet: connecting to multiple IEEE 802.11 networks using a single wireless card
TLDR
This work proposes a software based approach, called MultiNet, that facilitates simultaneous connections to multiple networks by virtualizing a single wireless card by introducing an intermediate layer below IP, which continuously switches the card across multiple networks. Expand
Low Latency Geo-distributed Data Analytics
TLDR
Iridium is presented, a system for low latency geo-distributed analytics that achieves low query response times by optimizing placement of both data and tasks of the queries and contains a knob to budget WAN usage. Expand
