Transformation patterns optimize transformations and improve their
internal structure. This paper presents an automatic method for pattern
proposition in transformation life cycles. Our approach combines the
transformation engineering by the idea of transformation patterns and
proposes appropriate patterns in the design and implementation phases of
transformation life cycle. We evaluate the impact of proposed patterns on
generated transformations based on several metrics, automatically. The
proposed patterns in the design phase are based on the structure of
transformation, and implementation patterns are proposed according to the
result of the evaluation. Our method is presented as a semi-automatic
process for using the transformation patterns in transformation life
cycles. The results of applying suggested patterns include decreasing the
complexity, memory usage, execution time, as well as increasing the
quality, efficiency, and modularity.

Privacy Aware Access Control: A Literature Survey and Novel Framework

Engineering and Technology, Chandigarh, India)

Due to the ever increasing number of web services available through the
Internet, the privacy as a fundamental human right is endangered. Informed
consent and collection of information are two important aspects while
interacting on the Internet through web services. The ease of data access
and the ready availability of it through Internet, made it easier for
interested parties to intrude into the individual's privacy in
unprecedented ways. The regulatory and technical solutions adopted to curb
this have achieved only a limited success. The main culprits in this
regard are the incompatibilities in the regulatory measures and standards.
This research work focuses on privacy preserving access control for
sharing sensitive information in the arena of web services, provides some
recent outlooks towards the critical need of privacy aware access control
technologies and a comprehensive review of the existing work in this
arena. Besides, a novel framework for privacy aware access to web services
is also provided.

Fault-Recovery and Coherence in Internet of Things Choreographies

Facilitating the creation of applications for the Internet of Things (IoT)
is a major concern to increase its development. D-LITe, our previous work,
introduces genericity by providing a universal programming interface.
Objects are dynamically configured to have their own behaviour, and their
actions/reactions are considered as part of a whole application. D-LITeful
Objects describe their capabilities, receives the application logic to be
executed, and interacts with other. The application is seen as a
choreography of behaviours. But the main issue of choreographies is the
loss of coherence. Because of their unreliability, some networks used in
IoT may introduce de-synchronization, leading to interactions errors. We
propose to reintroduce coherence in order to keep the advantages of
choreography while dealing with this main issue. An overlay of logical
check-points defines the dependence between the coherent states of objects
and triggers re-synchronizations. This paper ends with a discussion on the
trade-off between the checking cost and the reliability improvement.

Fog Caching and a Trace-Based Analysis of its Offload Effect

Marat Zhanikeev (Tokyo University of Science, School of Management, Tokyo,
Japan)

Many years of research on Content Delivery Networks (CDNs) offers a number
of effective methods for caching of content replicas or forwarding
requests. However, recently CDNs have aggressively started migrating to
clouds. Clouds present a new kind of distribution environment as each
location can support multiple caching options varying in the level of
persistence of stored content. A subclass of clouds located at network
edge is referred to as fog clouds. Fog clouds help by allowing CDNs to
offload popular content to network edge, closer to end users. However, due
to the fact that fog clouds are extremely heterogeneous and vary wildly in
network and caching performance, traditional caching technology is no
longer applicable. This paper proposes a multi-level caching technology
specific to fog clouds. To deal with the heterogeneity problem and, at the
same time, avoid centralized control, this paper proposes a function that
allows CDN services to discover local caching facilities dynamically, at
runtime. Using a combination of synthetic models and real measurement
dataset, this paper analyzes efficiency of offload both at the local level
of individual fog locations and at the global level of the entire CDN
infrastructure. Local analysis shows that the new method can reduce
inter-cloud traffic by between 16 and 18 times while retaining less than
30% of total content in a local cache. Global analysis further shows that,
based on existing measurement datasets, centralized optimization is
preferred to distributed coordination among services.
