countries, a large portion of the bottom-tier phones simply does not
offer that feature yet.GEMS is an end-to-end solution that addresses
this issue by enabling short messages - a quasi-omnipresent service
in all user segments and markets - to act as that transport. By
offering a client environment that mounts applications based on a
set of predefined UI components, it can make relatively complex
applications fit into a small number of concatenated SMS, thus
making a strong and practical app store statement for the long tail.
Application Defined Computing in Smartphones
and Consumer Electronics
Authors: Arun Jagatheesan, Zheng Li

Smartphones to enterprise servers, computing systems are built with
generic and commodity components, such as flash (NAND) storage,
memory, etc. Although such generalization of commodity
components reduces the cost of the product, generic components
result in severe inefficiency in terms of energy and performance. We
introduce Application Defined Computing (ADC) to specialize
generic hardware based on runtime application characteristics.
Our demonstration prototype and experimental results show that
brokering just a couple of parameters in DRAM (memory) systems
could improve Energy Delay Product by 23% and performance by
17% for smartphones. Our approach could be used in most
consumer electronics products with diverse application workloads.

Cloud resource provisioning is crucial to assure timely deliverable of
delay-sensitive cloud services. Today, virtual machine reservations are
done mainly based on cloud resource availability. Often, maximum VM
resources are preserved to assure service response time, resulting in
a waste of resources. Existing state-of-the-arts measure cloud
response time by deploying target applications on cloud infrastructure.
Such methods incur high overhead and useless for real-time
performance measurement for delay-sensitive application. In this
demo, we present a light-weight realtime service latency prediction
mechanism based on Euclidean Steiner Tree model for optimum VM
resource allocation in delay-sensitive cloud services. Our aim is to
derive a highly accurate service latency prediction mechanism
reflecting timely information of the actual cloud resources conditions,
while imposing minimum overheads to the cloud service. We present
a fast response cloud resource estimation system - FARCREST which
integrates the prediction model with cloud front-end server for VM
services latency prediction.
SDNAN: Software-Defined Networking in Ad
Hoc Networks of Smartphones

In this paper, SDNAN, a first attempt to implement software-defined
networking (SDN) over a wireless ad hoc network of smartphones, is
presented. Its modular ad hoc network management structure can be
easily modified and extended. Its abstractions and interfaces allow
components to communicate without knowing how other components
work. Third-party applications can use the interfaces to access the ad
hoc network, significantly reducing development time and program
complexity. A prototype system has been implemented on Android
smartphones over Wi-Fi and achieved good preliminary results.
Performance Improvement of Mobile P2P VoD
by Opportunity Extension

This demonstration introduces our on-going work called MOVi+ that
attempts to improve the video delivery performance of MOVi (Mobile
Opportunistic Video-on-demand) by scheduling segments from the
whole node perspective. By deploying segment based caching-enabled
switch, MOVi+ increases the opportunity which reflects the pairing
chances among nodes. MOVi+ also evaluates the merit of
pre-diffusion-aware scheduling to utilize the time varying opportunity
as much as possible. We shows that MOVi+ can eventually service
more number of mobile nodes than MOVi with lower segment missing
ratio, better opportunity usage, and playout continuity.

In this report, we introduce simple and efficient indoor navigation
prototype used for flying object. FINS model was built using Simulink
and USRP hardware. It includes accurate indoor GPS system and
flying system design. It is based on Pseudolite idea to solve the
problem of indoor location with high noise and multipath. It helps the
designer to make small helicopters as digital pixels of moving picture
in indoor environment which not easy to control, process and
communicate between them. The system can also use for many
indoor applications like for example tracking person or things in
hospital with high accuracy.
Enabling New E-health Business Models by
Converging IP-based and Non-IP-based Home

Current efforts in extending the Internet are focused on achieving full
support of services and user-centric content from sectors such as
energy management, education, and e-health. Until recently, these
sectors typically developed their own communication infrastructure
and systems, leading to point solutions, often built on non-IP
technologies. We describe a demonstration that shows how a non-IP
supporting Continua health device, such as a weighing scale, can be
unlocked for use by other devices and services in the home by
applying Universal Plug and Play (UPnP), and how this enables new
use cases and business models.
